Study Notes

Crystallization in Sugar Confections

Crystallization of sugar determines the subcategory of sugar confections it belongs to.
Controlled crystallization is essential for crystalline confections like fondants and fudge, creating smooth and creamy characteristics.
Crystallization must be avoided in noncrystalline confections like caramels, hard candies, and toffees, which have characteristics ranging from hard and brittle to soft and chewy.

Preventing Crystallization

Avoid impurities by using clean tools, equipment, and ingredients to prevent contamination.
Use a sugar source known to be pure to prevent contamination with flour or other impurities.

Temperature Control

Begin cooking at a medium-high temperature to prevent premature crystallization.
Increase temperature after the sugar solution has boiled, but avoid excessive heat.
Ensure even heat distribution when cooking with gas to prevent premature browning.

Sugar Grains

Ensure complete sugar dissolution before boiling to prevent undissolved sugar particles.
Wash down the sides of the pot with a clean pastry brush and water to remove any undissolved sugar particles.

Agitation

Avoid stirring sugar solutions after boiling to prevent crystallization.
Stirring can promote crystallization, unless specified in the formula.

Adding Doctors

Add additional ingredients like glucose, inverted sugar, or acids (like tartaric acid) to prevent crystallization.
Add doctors after the solution has come to a boil, as they can inhibit the bonding of sucrose molecules.
The molecular structures of glucose and inverted sugar can prevent crystallization by inhibiting sucrose molecule bonding.
Tartaric acid can help prevent crystallization by partially inverting the solution through hydrolysis.

Milk Chocolate

Made from chocolate liquor, sugar, milk solids, vanilla, and lecithin
Cocoa content can range from 10 to 45 percent
European-style milk chocolate is darker and may have a caramel taste due to high-temperature conching
In the United States, milk chocolate must contain at least 10 percent cocoa mass and 12 percent milk solids by law

White Chocolate

Not a true chocolate because it contains no cocoa solids
Made from cocoa butter, milk solids, sugar, and flavoring ingredients
Must contain at least 20 percent cocoa butter and 14 percent milk solids by FDA standards (revised in 2002)

Specialty Chocolates

Includes products like gianduja (milk chocolate combined with nut paste, usually hazelnut) and flavored chocolates (e.g., cappuccino, coffee, or orange)
This category is emerging as consumers become more aware of quality cocoa and more adventurous in taste
Some confectioners produce chocolate bars with additions like spices, dried fruits, and nuts, which are not regulated

Origin Chocolates

Made using beans from one growing region, resulting in uniquely flavored chocolate
Flavor highlights local cocoa varieties and production nuances, similar to estate wines
Prized for their unique and unadulterated flavor

Coating and Compound Chocolate

Made with cocoa butter equivalents (CBEs), designed for use without tempering
Can use palm kernel oil, a common CBE, which is fractionated to mirror cocoa butter's crystallization properties
Eliminates the need to temper the coating or compound chocolate after it has melted
Has a less appealing taste and mouthfeel compared to couverture due to higher melting point
Often used in conjunction with couverture for chocolate glazes, with a working temperature of 95°F (35°C)

Milk Chocolate

Made from chocolate liquor, sugar, milk solids, vanilla, and lecithin
Cocoa content can range from 10 to 45 percent
