✍️ Sample CPC Questions & Answers
1. What is the difference between baking soda and baking powder?
Baking soda is a pure alkaline compound (sodium bicarbonate) that requires an acidic ingredient, like buttermilk or lemon juice, to react and produce carbon dioxide for leavening. In contrast, baking powder is a complete leavening agent because it already contains both baking soda and a powdered acid, which react when moistened.
2. What is the 'Brix' measurement used for in sorbet and frozen dessert production?
Brix (°Bx) measures the percentage of soluble solids (primarily sugar) in a solution using a refractometer, used to standardize sorbet recipes for consistent texture.
3. In the production of croissants, what is a 'turn' or 'fold'?
Each 'turn' in laminated dough production involves folding the dough over itself (in thirds or quarters) and rolling it out, multiplying the number of butter-dough layers with each repetition.
4. Why is invert sugar (trimoline) sometimes used in place of part of the sucrose in sorbet recipes?
Invert sugar (a mix of glucose and fructose) depresses the freezing point more effectively than sucrose and does not crystallize, producing a smoother sorbet texture.
5. What is 'as-purchased (AP) weight' versus 'edible portion (EP) weight'?
AP weight is the total weight of an ingredient as purchased, while EP weight is what remains after trimming, peeling, or removing inedible parts — EP is used for accurate recipe costing.
6. What does 'bulk fermentation' refer to in bread production?
Bulk fermentation (first rise) is the period when the entire mixed dough rests and ferments before being divided and shaped.
