Baking and Pastry Operations Flashcards

A crème anglaise curdles during preparation. What temperature threshold was most likely exceeded?

Answer: 185°F (85°C), where egg yolk proteins over-coagulate

Crème anglaise must stay below about 185°F because yolk proteins curdle beyond that point.

Why is a baker's percentage system preferred in professional bread formulas?

Answer: All ingredients are expressed relative to flour weight, making scaling consistent

Baker's percentage states each ingredient as a percent of total flour weight, allowing accurate scaling of any batch size.

Which sugar cooking stage is required when preparing Italian meringue?

Answer: Soft ball stage, about 240°F (115°C)

Italian meringue is made by streaming soft-ball-stage syrup (approximately 240°F) into whipping egg whites.

A batch of muffins comes out with tough texture and elongated interior tunnels. What error in the muffin method most likely occurred?

Answer: The batter was overmixed after the liquid was added to the dry ingredients

Overmixing develops gluten in muffin batter, creating toughness and tunnels in the baked product.

What distinguishes puff pastry from croissant dough in composition?

Answer: Puff pastry contains no yeast and relies solely on steam for lift

Puff pastry is an unleavened laminated dough lifted only by steam, while croissant dough is yeast-leavened.

Which condition promotes desirable crust development and oven spring in hearth breads?

Answer: Injecting steam into the oven during the first minutes of baking

Early steam keeps the crust flexible for maximum oven spring and gelatinizes surface starch for a glossy, crisp crust.

Gelatin sheets must be prepared before being added to a warm bavarian base. What is the correct procedure?

Answer: Bloom the sheets in cold water, squeeze out excess, then dissolve in the warm base

Sheet gelatin is softened in cold water, wrung out, and then melted into a warm liquid to disperse evenly.
