BAKER’S CHOCOLATE or BAKING CHOCOLATE or BITTER CHOCOLATE or UNSWEETENED CHOCOLATE
A solid, bitter chocolate made from pure chocolate liquor, i.e., the cacao content is 100% with no sugar added. Historically, its only purpose was for baking. While it sounds like a generic term for chocolate used by bakers, the best-known brand is named for Dr. James Baker, a physician and owner, with John Hannan, of the first American chocolate mill. Baker’s Chocolate is now a trademark of Kraft Foods. There are other brands of baking chocolate, and today, the finest chocolate manufacturers are producing an unsweetened product, called 100% cacao content chocolate, that can be eaten as well. Some people who favor bittersweet chocolate enjoy the pureness of fine chocolate made with no sugar, as do diabetics who cannot have sugar. See also brut.

Baker’s Chocolate is named after chocolate manufacturer James Baker. |
NOTE: Greater Boston was the site of the first U.S. chocolate factories: in 1765, an Irish chocolate maker, John Hannan, put up a mill on the site of an old powder mill in Milton and imported cocoa beans from the West Indies to produce cakes of ground cacao bean paste used to make drinking chocolate. Other ventures sprouted up in the area. In 1780, Harvard graduate, teacher, and medical student James Baker saw the possibilities of the chocolate business and went into it with great success, producing the now-famous BAKER’S brand of chocolate. For the complete story, visit the Dorchester Atheneum. The brand is now owned by Kraft.

BAIN-MARIE
A bain-marie, or “Mary’s bath,” is the French equivalent of a double boiler. It melts chocolate gently over warm water so the chocolate will not burn. The “bath” refers to the method of placing a pan of food in another pan with simmering water. The term was originally used in alchemy and was named after Moses’s sister, who was an alchemist.

There are many types of bain-marie, but this one is good for home use (photo © Tescoma | Amazon).
A bain-marie is similar to a double boiler. The key difference is that with a bain-marie, the top pot with the contents is placed directly into the water. With a double boiler, the top pot doesn’t touch the water, so the contents are cooked with the steam generated between the top and the bottom. This is required, for example, with delicate egg-based sauces like Hollandaise, where direct contact with boiling water might curdle the eggs.
BALLOTIN
A ballotin is a box developed in Belgium with structured compartments designed to prevent pieces of chocolate from crushing each other. Unlike boxes that hold individual chocolate bonbons in ridged paper cups, chocolates in ballotins cannot move from their designated compartments. Ballotins are of elegant design, befitting their contents. The ballotin was invented in 1915 by Louise Agostini, whose husband, Jean Neuhaus Jr., was a grandson of the founder of Neuhaus Chocolates. Jean Neuhaus Jr., grandson of the founder of the famous Belgian chocolatier.
Before then, chocolates (specifically Belgian pralines, which is their word for filled chocolate shells) were sold in small, cone-shaped paper bags called cornet de frites (similar to the bags used for French fries). But because the bags were flexible and tapered, the weight of the chocolates on top would frequently crush the delicate shells of the ones at the bottom.
Jean Neuhaus, Jr. had invented the praline in 1912: a hard chocolate shell filled with ganache, creams, and other centers. After three years of watching these expensive new pralines get crushed in those paper bags, Louise Agostini took action.
She designed a rectangular, rigid cardboard box with a fold-over lid and internal dividers. This structure protected the chocolates and allowed them to be presented in tidy, attractive layers.

The term “ballotin” is a diminutive of the French word ballot, meaning a small bundle or package. Louise and Jean trademarked the design, and it quickly became the gold standard (no pun intended) for luxury chocolate packaging worldwide.
While Louise Agostini at Neuhaus trademarked the box style, it was Joseph Draps of Godiva who later popularized the “Gold Ballotin” in 1926, using the gold-colored box to signify royalty and extreme luxury. Today, almost every high-end chocolatier, from Läderach to Teuscher, uses a variation of Louise’s original 1915 design.
BARREL-AGED CHOCOLATE
As it does with wines and spirits, barrel-aging imparts a compiled array of flavors into coffee, cocktails, hot sauce, and other foods. Barrel aging can mellow the chocolate flavor while adding a hint of the spirit the barrel previously contained. Small artisan chocolatiers are creating bars from beans that are aged in wood barrels, where they pick up the natural notes of the wood barrel (like vanilla and oak) and hints of the bourbon, rum, or other spirit or ingredient that was previously stored in the cask. The flavor profile of barrel-aged chocolate is generally subtle, but some chocolatiers also soak the cacao beans with spirits while simultaneously aging them in the barrel. To’ak Chocolate in Quito, Ecuador, was a pioneer in creating barrel-aged chocolate. Beginning in 2013, the company has aged its beans in 15 varieties of barrels, specialty casks, and Ecuadorian wood for as long as four to five years [ source].

BÂTON
A French term for a slim bar of chocolate, a specialty size differentiated from a regular eating bar, which is called a tablette.
BEAN or CACO BEAN
Also called the grain, the seed of the cacao pod of the Theobroma cacao tree, beans are the source of all chocolate and cocoa. There are generally 20 to 40 flat, almond-shaped beans in a pod, depending on the species. When first picked, the beans have tropical flavors of lychee and pineapple, but in a few hours, the sugars convert, and they become bitter and inedible. Beans are then fermented, dried, roasted, ground, and conched to create chocolate. All cacao is grown in tropical rainforests; almost all of these are in third-world countries. Producers of chocolate purchase the beans through brokers who are on the ground in the countries of origin. Some cacao beans are purchased directly from small cooperatives of growers, others from individual farms, and in some countries, such as Ghana, the beans must be bought through a country's Cacao Board.
Cacao beans fall into four families: criollo (white or pale pink seeds), forastero (purple/brown seeds), criollo (a hybrid of the first two), and Nacional. You’ll find more about them in this glossary. The photo below, which shows white and brown beans in a single pod, is a criollo pod with both colors of seeds.

BEAN TO BAR
This term refers to a chocolate maker who makes chocolate from scratch, starting with the selection of raw cacao beans. The beans are then roasted and turned into couverture, the large blocks of chocolate that are then melted and used to make chocolate products—bars, bonbons, etc. Here is the chocolate production process. The alternative is to purchase ready-made couverture chocolate.
BELGIAN or BELGIAN-STYLE CHOCOLATE
Of the three styles of bonbons—Belgian, French, and Swiss—Belgian chocolates are characterized by a slightly larger size, a thicker chocolate shell, and a heavier and sweeter ganache. Belgian chocolates are made in molds, accounting for the thicker shell. The technique of molding was created by Belgian chocolatier Jean Neuhaus in 1912. who developed a process to pour couverture into molds, creating a hard shell, enabling softer, more liquid fillings like cremes to be used. Prior to then, firm centers like caramels, jellies, and thick ganaches were hand-dipped into the couverture. Some Belgian chocolatiers also use cookie pieces when creating certain chocolates. (Pierre Marcolini, who is also a patissier, does some wonderful pieces with cookies; although Marcolini, a Belgian, actually makes French-style chocolates).
BITTER CHOCOLATE
Another word for Baker’s chocolate or unsweetened chocolate.
BITTERSWEET CHOCOLATE
|
Sweetened dark chocolate contains at least 35% chocolate liquor, in addition to sugar and cocoa butter. The darkest chocolate with the most intense cacao flavor, bittersweet can also be used for baking. When expressed as a percentage of cacao in a bar, bittersweet chocolates have 70% or more. The common percentages of bars are 70%, 73%, 85%, 99%, and 100%. Percentages are based on the manufacturer’s preference and formula or “recipe.”
BLACK COCOA POWDER
Black cocoa powder is Dutched cocoa powder that has been heavily alkalized. It is more black than brown in color (think Oreos) and has a smoother taste with no bitterness. But it also tastes much less chocolatey.
The shade was invented because black food color tends to stain. Some bright person realized that a black-brown color could be achieved by treating natural cocoa with a stronger alkaline solution than is used for standard Dutched cocoa.
But the color comes at the cost of less acidity and less chocolate flavor. Also see red or rouge chocolate.
See how black the cocoa powder is in the dish below (Gemini Photo).

BLENDED BAR
A chocolate bar made of beans with any combination of bean varieties, growing regions, and harvest years. The opposite of a blended bar is a single-origin bar, where all of the beans come from the same area, or a grand cru bar, where all of the beans come from the same plantation or estate. Blended bars are sometimes called “house bars” because they are blended into a consistent recipe year after year to represent the house style of the producer.
BLENDING
The process that takes place with chocolate that is not a single bean, e.g., 100% Porcelana—i.e., most chocolate. After roasting and before grinding, the crushed cacao beans are blended in a formula or “recipe” determined by the master blender to determine the flavor of the finished chocolate. Since even beans from the same region can vary in flavor from harvest to harvest—acidic, fruity, earthy, sweet, bitter, spicy, woody, etc.—the blending process, along with the flavoring process, produces a consistent “house style.”
BLONDE CHOCOLATE, A.K.A. GOLD CHOCOLATE & DULCEY CHOCOLATE
Blonde chocolate was a happy accident. The famous French pastry chef Frédéric
Bau was in Japan for a chocolate trade fair. He let his white chocolate melt in a bain-marie a bit too long, which gave it a beautiful blonde hue and flavor and aroma notes of toasted shortbread and caramelized milk.
Frédéric Bau had discovered a fourth color for chocolate. It took Valrhona eight years of research and development to develop the final Blond Dulcey recipe, officially releasing it in 2012 as the first “blonde chocolate.”
The name Dulcey comes from Frédéric Bau, who named it after the French word “dulce,” meaning sweet or sugary.
His creation made blonde/dulce/gold chocolate the fourth variety, after dark, milk, and white chocolates. The fifth variety available today, ruby/rose chocolate, was introduced in 2017 by Barry Callebaut. It was developed from a special variety of ruby cocoa beans and has a natural pink color with a fruity, berry-like flavor. |

BLOOM
There are two kinds of bloom that form on the surface of chocolate: Both are temperature-related, and both make the chocolate look suspect and unappetizing. With fat bloom or cocoa butter bloom, the chocolate loses its gloss: A powdery grayish-white or tan film forms on the surface. This is due to improper storage, poor tempering, lack of tempering, or changes in temperature. Heating chocolate above 70°F, as well as repetitive heating and cooling, will cause microscopic cocoa butter particles to join together, leaving particles of sugar and cocoa uncoated. The bloom is the cocoa butter that has separated and risen to the surface. In some cases, the chocolate may become soft or crumbly. While bloom diminishes the appearance of the chocolate, it does not alter the taste and is not harmful. Chocolate with fat bloom can be eaten, although it may taste drier. Fat bloom can be avoided by storing chocolate at a constant temperature. Sugar bloom is caused by condensation due to excessive moisture. The moisture combines with the sugar in the chocolate to create a syrup. Large sugar crystals remain on the surface of the chocolate when the moisture evaporates. See Sugar Bloom for more information.

Bloom is a white, tan, or grayish film that appears on chocolate that isn’t well handled. Here’s more about it (photo © Bloom Chocolates).
BONBON or BON BON or PRALINE
French for “good, good,” a hard shell of chocolate filled with a variety of centers. The full French term is bonbon de chocolat (or chocolats fourrés assortis for assorted filled chocolates). It is referred to as praline in Belgium, while in France, a praline is a caramelized almond. To add to the confusion, the word truffle, which refers to balls of ganache rolled in cocoa powder or other coatings, is used by some to describe hard shells filled with ganache. Unfortunately, there is no governing body to standardize terminology, so consumers need to read the fine print to understand what they are buying. See the larger discussions under praline and truffle.

BOUCHON
A bouchon (BOO-shone), French for cork, is a molded, cork-shaped chocolate. It can be solid or filled. There are also bite-sized chocolate cakes by the same name. The bouchons in this photo are filled with hazelnut praliné (photo © Yves Thuries Chocolatier).

BOUTIQUE CHOCOLATIER
Often, the term “boutique chocolatier” is substituted for artisan chocolatier, but they are different. While an artisan sells his/her handmade wares in a small shop or boutique, anyone with no skills can open a shop or “boutique” that sells chocolate purchased from elsewhere, which is not necessarily handmade or artisan quality. (In fact, companies like Hershey’s have chocolate boutiques—shops that sell only their products.)
BRUT or BAKER’S CHOCOLATE
An FDA classification of chocolate that does not contain any sugar, though it may contain flavoring like vanilla. This pure chocolate was initially intended for cooking, but today, fine 100% cacao chocolate is enjoyed by many. See baker’s chocolate.
BUTTERFAT or BUTTER FAT or MILKFAT
The natural fat in milk from which butter is made is separable from the milk by churning. There is no butterfat in cocoa butter, which is a vegetable product. The French word for butterfat is graisse butyrique.
BUTTER OIL
Clarified butter is used instead of more expensive cocoa butter in some chocolate formulations to create a smoother texture and mouthfeel.
