Baking, Pastry, & Garde Manger Arts Flashcards

A baker wants to increase extensibility and reduce elasticity in bread dough. Which technique best accomplishes this?

Answer: Allowing an autolyse rest before mixing

Autolyse—resting hydrated flour before mixing—allows gluten to develop passively, breaking down some bonds and increasing extensibility while reducing dough toughness.

For a classic French pâté en croûte, the dough used must withstand extended baking without becoming soggy. Which dough is traditionally correct?

Answer: Hot water paste (pâte à pâté)

Hot water paste (pâte à pâté) is sturdy, minimally flaky, and stands up to the long baking and juices released by the forcemeat filling in a pâté en croûte.

During chocolate ganache preparation, an emulsion breaks and the mixture appears greasy and separated. What is the most effective corrective action?

Answer: Add a small amount of warm cream or water and blend with an immersion blender

Adding a small amount of warm liquid and blending with an immersion blender re-establishes the emulsion by reintegrating fat and water phases.

What is the function of cream of tartar (potassium bitartrate) when added to whipped egg whites?

Answer: It stabilizes the foam and lowers pH, strengthening the protein network

Cream of tartar is an acidulant that lowers egg white pH, which tightens the protein network and stabilizes the foam against over-whipping and collapse.

A garde manger chef is preparing a classic chaud-froid sauce to coat a display centerpiece. What gives white chaud-froid sauce its characteristic semi-opaque finish?

Answer: Béchamel or velouté combined with gelatin

White chaud-froid is made by fortifying béchamel or velouté with gelatin so it sets firmly when cold while retaining the sauce's opaque, creamy appearance.

A pastry chef needs to create a mirror glaze (glacage miroir) with a perfectly smooth finish. What is the critical step immediately before pouring the glaze onto a frozen cake?

Answer: Blending the glaze and straining it through a fine-mesh sieve to remove bubbles

Blending and fine-straining removes air bubbles that would create a pitted, dull surface, ensuring the glaze flows smoothly over the frozen mousse.

When scaling up a bread formula, which ingredient ratio must be recalculated rather than scaled linearly?

Answer: Salt and yeast

Salt and yeast are not scaled linearly in large batches because their effects are relative to fermentation kinetics and dough strength, not just weight; over-scaling yeast causes runaway fermentation.
