Baking, Pastry, & Garde Manger Arts Flashcards

A pastry chef is preparing a classic crème caramel. Why is the custard baked in a water bath (bain-marie)?

Answer: To regulate heat and prevent the custard from curdling by limiting the temperature to 100°C

A bain-marie caps the custard's maximum temperature at 100°C (the boiling point of water), preventing overheating that would cause proteins to curdle and produce a rubbery, weeping texture.

In garde manger, what is the primary purpose of curing a salmon fillet with salt and sugar (gravlax technique)?

Answer: To draw out moisture through osmosis, firm the texture, and preserve through reduced water activity

Salt and sugar cure by osmosis, drawing moisture from the fish, reducing water activity to inhibit microbial growth, and firming the flesh texture.

A pastry cook is making pâte de fruit and the final product is sticky and will not set. What adjustment should be made in a subsequent batch?

Answer: Add more pectin or cook the mixture to a higher Brix/temperature

Pâte de fruit requires sufficient pectin and a high enough sugar concentration (Brix) and temperature to create a firm gel; increasing either corrects a soft, sticky result.

Which bread pre-ferment is characterized by a stiff consistency (50–60% hydration) and contributes a slightly sweet, nutty flavor with a moderate fermentation window?

Answer: Biga

Biga is an Italian stiff pre-ferment (50–60% hydration) that ferments slowly, producing a mild, slightly sweet flavor profile favored in ciabatta and other Italian breads.

When fabricating a classic aspic for a garde manger display, a chef achieves clarity through clarification. What proteins are used to trap impurities in the raft?

Answer: Egg whites (albumen) combined with lean ground meat (clearmeat)

Clarification uses a clearmeat of lean ground meat and egg whites; as the mixture heats, proteins coagulate and form a raft that adsorbs impurities, yielding a crystal-clear aspic.

A pastry chef is scaling a soufflé recipe for 50 covers. Which component ratio is most critical to maintain precisely to ensure proper rise?

Answer: The ratio of whipped egg whites to base, and the timing of folding and baking

The proportion of whipped egg whites to the base and the immediate baking after folding are critical because the foam structure—not the base composition—drives soufflé rise.

In CMC-level pastry work, what distinguishes a diplomat cream (crème diplomate) from a mousseline cream (crème mousseline)?

Answer: Diplomat cream is pastry cream lightened with whipped heavy cream and stabilized with gelatin; mousseline is pastry cream beaten with softened butter

Crème diplomate folds gelatin-stabilized pastry cream with whipped heavy cream for a light, mousse-like texture, while crème mousseline incorporates softened butter for richness and stability.
