1.
A custard is any liquid thickened by the coagulation of egg proteins.
Correct Answer
A. True
Explanation
The statement is true because custard is indeed a liquid that is thickened by the coagulation of egg proteins. The proteins in the eggs help to give custard its thick and creamy texture when cooked. Without the coagulation of the egg proteins, the liquid would remain thin and runny. Therefore, custard is a type of dessert or sauce that is made by combining eggs with a liquid and heating it until it thickens.
2.
The more eggs used, the richer and thicker the custard will be.
Correct Answer
A. True
Explanation
Using more eggs in a custard recipe will result in a richer and thicker custard. Eggs contribute to the creamy texture and add richness to the custard. They also act as a binding agent, helping to thicken the custard as it cooks. Therefore, increasing the number of eggs used in the recipe will enhance the overall texture and flavor of the custard, making it richer and thicker.
3.
What are some ways to make a thicker custard?
Correct Answer(s)
A. Using more eggs
B. Using a richer liquid such as cream (as opposed to milk)
Explanation
Using more eggs and using a richer liquid such as cream will both contribute to making a thicker custard. Eggs contain proteins that coagulate when heated, helping to thicken the custard. Adding more eggs will increase the amount of protein available for coagulation, resulting in a thicker consistency. Similarly, using a richer liquid like cream, which has a higher fat content than milk, will also contribute to a thicker texture as the fat helps to emulsify and stabilize the custard. Using less liquid overall will also result in a thicker custard as there is less liquid to dilute the thickening agents.
4.
Most custards are thickened with a starch.
Correct Answer
B. False
Explanation
In general, custards don't need a starch thickening agent. Pastry creams are a notable exception.
5.
Custards can be baked in the oven or cooked on a stove top.
Correct Answer
A. True
Explanation
Custards can be prepared using two different methods: baking in the oven or cooking on a stove top. Both methods yield delicious custards, allowing for flexibility in preparation based on personal preference or available cooking equipment. Therefore, the statement "Custards can be baked in the oven or cooked on a stove top" is true.
6.
When cooking a custard on a stove top, why is it important to keep stirring the mixture?
Correct Answer
C. To stabilize the eggs and prevent curdling.
Explanation
When cooking a custard on a stove top, it is important to keep stirring the mixture to stabilize the eggs and prevent curdling. Stirring the custard ensures that the eggs are evenly distributed throughout the mixture and prevents them from cooking too quickly or curdling. This helps to create a smooth and creamy texture in the custard, rather than a lumpy or curdled consistency.

When making a custard sauce, a small portion of the heated milk mixture is stirred into the yolks. Then the yolk mixture is stirred into the heated milk. This step is called ______ and helps raise the temperature of the eggs without causing them to curdle.
Correct Answer
A. Tempering
Explanation
Tempering is the correct answer because it refers to the process of gradually raising the temperature of one ingredient by adding a small amount of a hot liquid to it. In this case, a small portion of the heated milk mixture is added to the yolks to increase their temperature slowly, preventing them from curdling when they are then added to the heated milk. This technique is commonly used in cooking to ensure that ingredients with different temperatures can be combined without any adverse effects.
8.
When making custard, it's important to prevent the eggs from curdling. What does curdling mean in this context?
Correct Answer
B. To coagulate or congeal.
Explanation
Curdling in the context of making custard refers to the process of coagulating or congealing the eggs. When eggs curdle, they solidify and form lumps, which can ruin the texture of the custard. Therefore, it is important to prevent curdling by slowly adding the hot liquid to the eggs and constantly stirring to evenly distribute the heat and prevent the eggs from coagulating too quickly.
9.
When making a custard sauce, do not allow the temperature to exceed ____ or the custard will break.
Correct Answer
A. 190 degrees F.
Explanation
When making a custard sauce, it is important not to allow the temperature to exceed 190 degrees F. If the temperature goes beyond this point, the custard will break. This means that the emulsion of the sauce will separate, resulting in a grainy and curdled texture. By keeping the temperature below 190 degrees F, the custard will maintain its smooth and creamy consistency.

21.
What is the cause of an undesirable watery custard?
Correct Answer
B. Custard overcooked
Explanation
When custard is overcooked, it can cause the proteins in the eggs to denature and coagulate excessively, resulting in a watery consistency. Overcooking can also cause the starch in the custard to break down, leading to a loss of thickening power and a runny texture. Therefore, custard that is overcooked is likely to become watery and undesirable.
22.
The custard sauce is lumpy. What happened?
Correct Answer
C. Sugar and yolks were not mixed properly.
Explanation
The custard sauce is lumpy because the sugar and yolks were not mixed properly. When making custard, it is important to thoroughly mix the sugar and yolks together to ensure a smooth and creamy texture. If they are not properly mixed, it can result in lumps forming in the sauce. Overcooking the custard or having too much fat in it would not directly cause lumps in the sauce.
23.
The baked custard is curdled. What happened?
Correct Answer
B. Custard was overcooked.
Explanation
The custard being overcooked can cause it to curdle. Overcooking can cause the proteins in the custard to denature and separate from the liquid, resulting in a curdled texture. This can happen if the custard is cooked at too high of a temperature or for too long. Mixing the custard properly and the amount of fat in it are not directly related to it curdling.
24.
What are the most likely causes for a pastry cream that is too runny?
Correct Answer(s)
A. Not enough starch.
B. Undercooked starch.
C. Wrong starch was used.
D. Overstirring.
Explanation
The most likely causes for a pastry cream that is too runny are not enough starch, undercooked starch, wrong starch being used, and over-stirring. These factors can affect the thickening properties of the starch in the cream, leading to a runny consistency. Not enough starch or undercooked starch may result in insufficient thickening, while using the wrong starch or over-stirring can disrupt the starch's ability to form a proper gel structure, causing the cream to be runny. Too much fat, on the other hand, is not mentioned as a likely cause for a runny pastry cream.
