Explanations: answer key for all 10 questions

Q1: Which reaction between sugars and amino acids browns crust?
Answer: Maillard reaction
It creates many flavors.
Q2: Which other browning involves sugar alone?
Answer: Caramelization
It needs higher heat.
Q3: Why do bakers add steam early in baking?
Answer: To keep the surface soft for oven spring
The loaf can expand more.
Q4: What does early steam give a baguette crust?
Answer: A crisp, shiny finish
Starches gelatinize on the surface.
Q5: Why do bakers score loaves?
Answer: To control where the loaf expands
Slashes guide the opening.
Q6: What is the raised flap from a score called?
Answer: An ear
It is prized on sourdough.
Q7: What does an egg wash give a crust?
Answer: A glossy brown finish
Proteins help browning.
Q8: Why does crust soften in a plastic bag?
Answer: Moisture from the crumb moves outward
Paper bags keep it crisper.
Q9: What makes a cooling loaf crackle or sing?
Answer: The crust cracking as it cools
Tiny cracks form.
Q10: Why is a hot oven important for crust?
Answer: Browning reactions need high heat
Low heat gives pale crusts.

The Crackle of a Fresh Loaf

Bread crust gets its color and flavor from browning. The Maillard reaction between sugars and amino acids creates hundreds of flavor compounds, while caramelization of sugar adds more at higher temperatures. A hot oven is essential, since low heat gives pale, bland crusts.

Bakers add steam early in baking to keep the surface soft, letting the loaf expand in oven spring. Steam also helps starches on the surface gelatinize, giving baguettes their crisp, shiny crust. Scoring with a blade controls where the loaf opens, and a raised flap called an ear is prized on sourdough. An egg wash gives a glossy brown finish.

As bread cools, the crust cracks with a faint crackle, often called singing. Stored in a plastic bag, the crust softens as moisture moves out from the crumb, so paper bags keep it crisper for longer.
