When baking for Chocolate Day, understanding which chocolate products work best will make your dessert taste good and have an ideal texture. The flavour of cocoa powder is intense and allows for control of sweetness. Chocolate chips are manufactured to retain their shape during baking, whereas cocoa nibs add crunch and a strong cocoa flavour. Lastly, chocolate bars (especially couverture) melt nicely and add richness to the flavour.
Whether you’re making something special for Chocolate Day or simply baking something you enjoy, knowing how different types of chocolate react can help you tremendously. The flavour and texture of chocolate can vary greatly based on its form (cocoa, chocolate chips, chocolate nibs, chocolate bars) and its type (dark, milk, and white). This article describes how the different types of chocolate perform in food preparation and flavour. This information will benefit new bakers and those looking to create exceptional desserts for Chocolate Day and other occasions.
With a robust chocolate flavour and a minor fat content, cocoa powder provides bakers the flexibility to adjust the level of sweetness and texture exactly as they want. There are two types of cocoa powder: natural (bright flavour, acidic) and Dutch-processed (mellow flavour, neutral in acidity, dark in colour), both of which affect how cocoa powder interacts with the leavening agents available during baking.
When baked, chocolate chips retain their shape by virtue of having slightly lower levels of cocoa butter and stabilising agents in comparison to bar chocolates. This makes them a perfect fit for muffins, cookies and quick breads. Different styles of chips (dark, milk, and white) effect different levels of sweetness and melting behaviour to food products because dark chips will give you a more dense, rich product with a firmer bite due to their high cocoa solids and higher percentage of cocoa butter; whereas white chips contain no cocoa solids so they produce a creamy sweet chip with limited melting behaviour when compared to dark or milk chips.
Cocoa nibs, chunks of roasted or hulled cacao beans, provide a pronounced bitterness and a crunchy texture when added to desserts, thus adding complexity and depth to the flavour of many dessert items. Interestingly enough, cocoa nibs do not have any sugar in them and can therefore be used as an inclusion, providing a chocolate punch to baked goods, yet not altering the overall sugar content in the final product.
There are many types of chocolate bars, each with different ratios of cocoa solids to sugar. Dark chocolate bars contain a high percentage of cocoa (in the 50%-90% range), yielding rich, complex flavour profiles; while milk chocolate bars provide a creaminess associated with the addition of milk powder. White chocolate contains no cocoa solids; rather, its flavour comes solely from the dairy or sugar added to the product. Chocolate is often referred to as a "couverture" if it has a high fat and/or cocoa butter content. High-fat chocolates melt smoothly; therefore, they create beautifully glossy ganaches and chocolate coatings that are great for desserts on Chocolate Day.
When melted, the physical properties of chocolate differ due to the ratio of cocoa to sugar. Firm-set dark chocolate has the highest concentration of cocoa solids, making it the firmest type of chocolate; while soft-set milk chocolate has higher fat content (due to the addition of milk) and creates the softest, meltable candy bars. Because of their high butter content, white chocolates feel extremely luxurious, like biting into a slice of butter. The way chocolate behaves in batters, glazes, and fillings will be dictated by the specific characteristics of each type of chocolate used in the application; therefore, selecting the correct type of chocolate is of utmost importance when working towards achieving the desired result.
Understanding the properties of chocolate on Chocolate Day involves both the scientific and artistic aspects of making chocolate. The cocoa solids, cocoa butter, sugar, and milk solids (when used) are necessary to create the flavour and texture of chocolate. Cocoa powder has had most of its fat removed giving a more intense flavour of chocolate; chocolate chips are created to hold their shape; cocoa nibs (the unsweetened bits from a cocoa bean) contain many of the natural flavour characteristics of chocolate, and also some crunchy texture; and chocolate bars and couverture have the same amount of cocoa butter and solids, enabling each to behave similarly when melted; so that you can use either of them to make sauces, ganaches or coatings.
Because of these differences, substituting a different form of chocolate (milk chocolate chips for dark chocolate bars) will greatly affect both the flavour and texture of the finished product. Using the correct form of chocolate for your use will not only enhance its flavour, but will also improve its texture, mouthfeel and baking chemistry.
