CC Stocks, Sauces & Soups 1 — Questions and Answers
Question 1: What is the primary purpose of roasting bones before making brown stock?
- To develop rich color and complex flavors through the Maillard reaction (Correct answer)
- To sterilize the bones and remove harmful bacteria
- To reduce the total cooking time of the stock
- To extract more gelatin from the connective tissue
Correct answer: To develop rich color and complex flavors through the Maillard reaction
Roasting bones caramelizes proteins and sugars through the Maillard reaction, developing the deep brown color and rich, complex flavors characteristic of brown stock.
Question 2: What is the classical French aromatic vegetable base of two parts onion, one part carrot, and one part celery used in stock and sauce preparation?
- Bouquet garni
- Mirepoix (Correct answer)
- Sachet d'épices
- Soffritto
Correct answer: Mirepoix
Mirepoix is the classic French aromatic base of two parts onion, one part carrot, and one part celery used to build flavor in stocks, soups, braises, and sauces.
Question 3: What is the approximate simmering time recommended for a properly made white chicken stock?
- 30 minutes to 1 hour
- 3 to 4 hours (Correct answer)
- 8 to 10 hours
- 12 to 24 hours
Correct answer: 3 to 4 hours
White chicken stock should simmer 3 to 4 hours to extract maximum flavor and gelatin; longer cooking can produce a bitter, cloudy stock.
Question 4: What is a sachet d'épices in stock preparation?
- A type of French herb vinaigrette used to finish sauces
- A clarification agent made from ground meat and egg whites
- A cheesecloth bundle of herbs and spices used to infuse flavor into stocks (Correct answer)
- A mixture of butter and flour used to thicken sauces
Correct answer: A cheesecloth bundle of herbs and spices used to infuse flavor into stocks
A sachet d'épices is a small cheesecloth bundle typically containing parsley stems, bay leaf, thyme, peppercorns, and garlic, used to infuse flavor into stocks without loose particles.
Question 5: Why should stock always be started in cold water rather than hot water?
- Cold water prevents the bones from shrinking during cooking
- Cold water allows proteins and impurities to gradually rise to the surface for skimming (Correct answer)
- Cold water extracts significantly more gelatin from the bones
- Hot water would instantly make the stock too salty
Correct answer: Cold water allows proteins and impurities to gradually rise to the surface for skimming
Starting stock in cold water allows proteins and impurities to gradually dissolve and coagulate as the temperature slowly rises, making them easier to skim off the surface for a clearer finished stock.
Question 6: What gives fish stock (fumet) its distinctly shorter cooking time of 20–30 minutes compared to veal or beef stock?
- Fish bones have a much higher water content than mammal bones
- Fish stock uses a higher proportion of vegetables than meat stocks
- Fish bones are delicate and quickly release flavor, while prolonged cooking extracts bitter compounds (Correct answer)
- Fish stock requires lower simmering temperatures that slow the extraction process
Correct answer: Fish bones are delicate and quickly release flavor, while prolonged cooking extracts bitter compounds
Fish bones are fragile and release flavor compounds quickly; cooking fish stock longer than 20–30 minutes extracts bitter compounds from the bones and gills, resulting in an off-flavored product.
Question 7: What is the purpose of blanching bones before making a white stock?
- To develop additional flavor through caramelization of bone surfaces
- To remove excess salt absorbed during the aging of the bones
- To remove blood, impurities, and off-flavors that could cloud the finished stock (Correct answer)
- To soften the bones so gelatin extracts more quickly during simmering
Correct answer: To remove blood, impurities, and off-flavors that could cloud the finished stock
Blanching bones in rapidly boiling water for a few minutes removes blood, soluble proteins, and off-flavors that would otherwise cloud the stock or contribute unpleasant flavors.
