CRM Advanced Cooking Techniques & Methods 3 — Questions and Answers
Question 1: What distinguishes 'dry heat' cooking methods from 'moist heat' methods?
- Dry heat uses fats or air; moist heat uses water-based liquids (Correct answer)
- Dry heat is always faster than moist heat
- Moist heat requires higher temperatures than dry heat
- Dry heat is used only for vegetables, moist heat only for proteins
Correct answer: Dry heat uses fats or air; moist heat uses water-based liquids
Dry heat cooking (roasting, grilling, sautéing) uses hot air, radiation, or fat, while moist heat (braising, poaching, steaming) uses water or stock as the cooking medium.
Question 2: A chef uses transglutaminase ('meat glue') in a fine dining preparation. What is the primary purpose?
- To tenderize tough cuts by breaking down collagen
- To bind protein pieces together seamlessly (Correct answer)
- To add umami flavor to lean proteins
- To extend the shelf life of raw proteins
Correct answer: To bind protein pieces together seamlessly
Transglutaminase is an enzyme that creates bonds between protein molecules, allowing chefs to fuse trim or multiple cuts into a seamless, uniform piece.
Question 3: Which of the following best explains the Maillard reaction?
- Caramelization of natural sugars under high heat
- A chemical reaction between amino acids and reducing sugars producing brown color and complex flavors (Correct answer)
- The gelatinization of starches in bread crust
- The oxidation of fats that creates a golden color
Correct answer: A chemical reaction between amino acids and reducing sugars producing brown color and complex flavors
The Maillard reaction is a chemical interaction between amino acids and reducing sugars at high temperatures that creates hundreds of flavor and aroma compounds plus brown color.
Question 4: In molecular gastronomy, 'spherification' is used to create caviar-like spheres. What gelling agent is traditionally used in basic spherification?
- Agar-agar
- Sodium alginate and calcium chloride (Correct answer)
- Gelatin and citric acid
- Carrageenan and potassium chloride
Correct answer: Sodium alginate and calcium chloride
Basic spherification uses sodium alginate dissolved in liquid, which forms a gel membrane when dropped into a calcium chloride bath.
Question 5: What is the key difference between 'braising' and 'stewing'?
- Braising uses whole or large cuts partially submerged; stewing uses small pieces fully submerged (Correct answer)
- Braising is done on the stovetop; stewing is always done in the oven
- Braising uses only vegetables; stewing uses only meats
- Braising requires a longer cook time than stewing
Correct answer: Braising uses whole or large cuts partially submerged; stewing uses small pieces fully submerged
Braising uses larger cuts partially covered in liquid with a tight lid, while stewing uses smaller, uniform pieces fully submerged in liquid.
Question 6: A cook notices that a beurre blanc sauce has broken and appears greasy. What most likely caused this?
- Too much lemon juice was added
- The sauce got too hot, causing the emulsion to separate (Correct answer)
- The butter was too cold when incorporated
- The shallots were not strained out properly
Correct answer: The sauce got too hot, causing the emulsion to separate
A beurre blanc breaks when overheated because excessive temperature destroys the emulsion, causing butter fat to separate from the water-based reduction.
Question 7: Which technique involves repeatedly folding and resting dough to develop gluten structure in croissant production?
- Lamination (Correct answer)
- Autolysis
- Scoring
- Proofing
Correct answer: Lamination
Lamination is the process of folding butter-encased dough multiple times to create hundreds of thin, distinct layers that produce flaky croissants.
