Answers and explanations appear as you take the quiz.

1. About how much more area does a 9-inch round pan have than an 8-inch round pan?
   • About 12 percent
   • About 27 percent
   • About 50 percent
   • About 100 percent
2. Why doesn't a double batch of stew need double the total cooking time?
   • Heat reaches the center based mostly on thickness, not on the total amount
   • Larger pots always run hotter
   • The AI automatically lowers the temperature
   • Stew ingredients cook faster in large batches because of added salt
3. You're halving a recipe that calls for 3 eggs. What does the guide suggest?
   • Use 1 egg and add water
   • Use 2 eggs, since rounding up is harmless
   • Skip the eggs and add baking powder
   • Beat the eggs and weigh about 75 g, since a large egg is roughly 50 g out of the shell
4. Doubling a brownie recipe from an 8x8 pan into a 9x13, what should you expect?
   • The batter will be much thinner and bake twice as fast
   • The two pans hold exactly the same amount
   • The batter will be slightly deeper, because 117 sq in is a bit less than 128 sq in
   • The 9x13 pan cannot be used for brownies
5. In baker's percentages, each ingredient is expressed relative to what?
   • The total weight of the dough
   • The weight of the flour
   • The number of servings
   • The weight of the water
6. What is the correct result of scaling 3/4 cup by 2.5?
   • 1 1/2 cups
   • 1 3/4 cups
   • 2 cups
   • 1 7/8 cups
7. Tripling a soup in a wider pot changes simmering how?
   • Evaporation slows, so the soup gets thinner
   • Nothing changes, because volume is all that matters
   • Evaporation speeds up because of the larger surface area
   • The soup must simmer three times as long
8. To keep the same batter depth when scaling a recipe by 1.5x, how should the new pan's area compare with the original?
   • It should be 1.5 times the original area
   • It should be the same as the original
   • It should be 2.25 times the original area
   • It should be 3 times the original area
