Cooking Lessons Cooking Knowledge 5 — Questions and Answers
Question 1: You taste a soup and it is too salty. Which fix is most effective?
- Add more unsalted liquid or bulk ingredients to dilute it (Correct answer)
- Chill the soup so the salt settles to the bottom
- Boil it harder to evaporate the salt
- Add more salt to balance the flavor
Correct answer: Add more unsalted liquid or bulk ingredients to dilute it
Salt cannot be removed, so diluting with unsalted stock, water, or extra ingredients is the reliable fix.
Question 2: What is the Maillard reaction?
- The melting of fat at high temperatures
- The rising of dough caused by yeast
- The curdling of dairy in acidic sauces
- A browning reaction between amino acids and sugars that creates savory flavor (Correct answer)
Correct answer: A browning reaction between amino acids and sugars that creates savory flavor
The Maillard reaction browns proteins and sugars under heat, producing complex roasted flavors.
Question 3: Which herb is best added at the end of cooking because heat destroys its delicate flavor?
- Dried oregano
- Whole rosemary sprigs
- Fresh basil (Correct answer)
- Bay leaf
Correct answer: Fresh basil
Tender herbs like basil lose their aroma quickly with heat, so they are stirred in just before serving.
Question 4: When making stock, why should you skim the foam that rises to the surface?
- Skimming makes the stock cook faster
- The foam contains impurities that can make the stock cloudy and bitter (Correct answer)
- The foam is toxic if consumed
- The foam prevents the pot from boiling
Correct answer: The foam contains impurities that can make the stock cloudy and bitter
Skimming coagulated proteins and impurities keeps the finished stock clear and clean-tasting.
Question 5: A cake recipe says to cream butter and sugar. What does this step accomplish?
- It melts the butter for easier mixing
- It chills the batter before baking
- It beats air into the fat to help leaven and lighten the cake (Correct answer)
- It dissolves the sugar into syrup
Correct answer: It beats air into the fat to help leaven and lighten the cake
Creaming whips tiny air pockets into the butter, which expand during baking for a light crumb.
Question 6: What internal temperature indicates ground beef is safely cooked?
- 145°F
- 135°F
- 120°F
- 160°F (Correct answer)
Correct answer: 160°F
The USDA requires ground beef to reach 160°F because grinding spreads surface bacteria throughout.
Question 7: Why does a cast-iron skillet need to be seasoned?
- Seasoning adds salt flavor to every dish
- It makes the pan lighter and easier to handle
- Baked-on oil layers create a natural nonstick surface and prevent rust (Correct answer)
- It sterilizes the pan before first use
Correct answer: Baked-on oil layers create a natural nonstick surface and prevent rust
Seasoning polymerizes oil into a protective nonstick coating that also guards against rust.
