Cooking Chocolate

On World Chocolate Day: Its Composition, Uses, And More

Quick Summary

The chocolate bars that are sold to you via compelling marketing can be quite a costly investment if you are cooking with chocolate. Luckily, there are different types of chocolate with different grades, including cooking chocolate and compound chocolate. The cocoa butter content of cooking chocolate is low; it has more cocoa solids and is low in sugar, unlike regular chocolate bars. It is engineered in a way that it melts easily and can be used in a variety of dessert recipes.

Deep Dive

This World Chocolate Day, here’s a deep dive into cooking chocolate, its composition and how the ratio of cocoa solids, cocoa butter, sugar and milk solids separates it from dark, milk and white chocolate. This also decides how each chocolate will behave and perform in confection making. As for dark chocolate, it has a high proportion of cocoa solids and cocoa butter with little to no milk; milk chocolate has sufficient cocoa content with milk solids and added sugar, and white chocolate has no cocoa solids, relying only on cocoa butter for it to be characterised as chocolate.

Beyond the three basic types of chocolate, professional confectionery making depends on another distinction between two types of cooking chocolates, and this time it comes down to the quality. There is couverture chocolate versus compound chocolate; the former is a premium cooking chocolate because of its high cocoa butter content, while the latter usually substitutes it with vegetable fats and is of lower quality. This sole factor determines if chocolate needs tempering at all. This article breaks down the exact percentages behind each chocolate type, explains the impact of the cocoa butter content, and covers where cooking chocolate shows up outside of desserts entirely.

What is Chocolate Made of?

Chocolate has four basic components that determine its grade and how your dessert will turn out to be. The proportion of each is what defines whether a bar is labelled dark, milk or white.

• Cocoa solids: These are the non-fatty portion of the cocoa bean left after cocoa butter is extracted. They give chocolate its characteristic colour, flavour, aroma, and slight bitterness. The higher the cocoa solids content, the richer and more intense the chocolate's flavour tends to be. 

• Cocoa butter: Cocoa butter is the natural fat found in cocoa beans, accounting for around half of the bean's weight. It is responsible for chocolate's smooth texture, glossy finish, and the characteristic ‘snap’ of well-tempered chocolate. Cocoa butter influences the melting point of the chocolate during tempering and is also behind that velvety finish and a signature melt-in-the-mouth quality.

• Sugar: Cocoa is bitter, and most chocolate bars have some amount of added sugar in them. The sugar is dispersed throughout the cocoa butter, which helps create a smooth mouthfeel.

• Milk solids: These are dehydrated milk, which includes milk proteins, lactose (milk sugar), and minerals. They are added to milk and white chocolate, contributing to a creamier texture, lighter colour, and milder flavour.

Cooking chocolate also comes in different forms, from dark chocolate, white chocolate, to milk chocolate wth caring levels of sugar, milk solids, cocoa solids and cocoa butter, or rather vegetable fats.

Cooking Dark Chocolate’s Composition

You need to read the label before buying dark cooking chocolate, as this one’s typically the costliest option. The cocoa percentage printed on the pack will tell you how it will behave in a recipe, not just how it will taste. 

• A bar labelled 70% contains 70% combined cocoa solids and cocoa butter, with the rest made up mostly of sugar.

• A higher cocoa-to-sugar ratio is why dark cooking chocolate is the default for ganache, brownies and dense chocolate cakes.

• Dark cooking chocolate will hold itself well and doesn't add any sugar, so there is no excess sweetness to compete with other ingredients. 

Two bars at the same cocoa percentage can still behave differently during tempering, and the difference lies in the internal split between cocoa solids and cocoa butter. Cooking chocolate with more cocoa butter melts more smoothly and is easier to work into a glaze. A chocolate with more solid cocoa mass gives a firmer set, better suited to a brownie batter that needs to hold its shape.

Cooking Milk Chocolate Differs in Composition

Milk chocolate reserved for cooking sits in the 30-50% cocoa range, with milk solids and extra sugar filling out the rest. That composition changes how it needs to be handled compared to dark chocolate. Because it contains more sugar and milk solids and less cocoa mass, milk chocolate scorches more easily over heat and needs to be tempered using a double boiler or in short intervals in a microwave.

Milk chocolate cannot be melted straight into a hot pan, like the way dark chocolate sometimes can, because of the milk solids and sugar in it. In baking, milk chocolate is rarely used as the sole chocolate source in a cake or brownie recipe, since its lower cocoa content produces a softer, less structured bake. It is perfect for use in cookie doughs, mousse, or paired with dark chocolate to soften its intense flavour.

What Makes White Chocolate Different From the Other Two?

White cooking chocolate has no cocoa solids and relies only on cocoa butter (a minimum of 20% by most standards) along with milk solids and sugar, and this absence of cocoa solids is what makes it trickier to cook with than dark or milk chocolate. Without cocoa solids acting as a stabiliser, white chocolate is far more sensitive to overheating and can turn into a grainy, unusable mass much faster than dark chocolate does. 

This is why recipes calling for melted white chocolate usually specify low, indirect heat, like using the bain-marie (double boiler method). Its high cocoa butter content also makes it useful in a different way, which can be used to enrich or thin out other chocolate mixtures, or as a base for tinted, coloured coatings in confectionery work, since it takes food colouring far better than dark or milk chocolate ever can.

How is Cooking Chocolate Used in Confection Making?

World Chocolate Day deserves your time to take a tour of professional confectionery making. The chocolate used is cooking chocolate, and depending on the confection, the type of chocolate changes. The composition of chocolate determines whether it needs to be tempered before use. This is where the distinction between couverture chocolate versus compound chocolate (the most used cooking chocolate) comes in. 

Couverture chocolate is made using cocoa butter as its primary fat, generally 30% or more by weight, and this high cocoa butter content is what gives couverture its glossy shine, the perfect snap, and smooth melting quality, once tempered properly. Skip the tempering, and the chocolate can develop a dull, chalky surface with poor setting.

Compound chocolate substitutes the cocoa butter in couverture chocolate with vegetable fats such as palm kernel oil, which means it does not need tempering and can simply be melted and used directly. This makes it far more practical for high-volume or beginner-level work, but it comes at the cost of flavour and that signature snap when broken. 

Couverture remains the preferred choice for confection-making for expert dessert makers. It is used to make truffles, bonbon shells, and chocolates which call for tempered couverture, while compound chocolate is used for cake pops, dipped biscuits, and mass-produced coatings where cost and convenience outweigh finesse.

How to Use Cooking Chocolate Beyond Desserts

Cooking chocolate's use isn't limited to just desserts, it can be used to make ganache, which is a simple emulsion of chocolate and cream, and one of the most versatile ingredients that is used to an entire dessert, used as a cake filling, can be used as a glaze, frosting, or the base for rolled truffles, depending only on the ratio of chocolate to cream used. You can also use it to make chocolate beverages like hot chocolate.

Besides this, chocolate also has a long-standing role in savoury cooking and goes into Mexican mole sauces, where it’s a defining ingredient. A small addition near the end of cooking to add depth, rather than sweetness. Some cooks add a bit of unsweetened chocolate to chilli con carne and even bolognese sauce to make it less acidic, without making the dish sweet or tasting like chocolate.

Celebrating World Chocolate Day with Cooking Chocolate

Cooking chocolate's behaviour in any recipe comes down almost entirely to its composition, with the ratio of cocoa solids, cocoa butter, sugar and milk solids that separates dark, milk and white chocolate. The presence or absence of cocoa butter that separates couverture from compound. Understanding those percentages and their differences will make your baking and cooking journey smoother this World Chocolate Day.
