CPC Frozen Desserts & Ice Cream 1 — Questions and Answers
Question 1: What is the primary difference between ice cream and gelato?
- Gelato contains more cream; ice cream contains more milk
- Gelato has less fat, less air (overrun), and is served at a warmer temperature than ice cream (Correct answer)
- Ice cream uses eggs; gelato does not use any eggs
- Gelato is always fruit-flavored; ice cream is always dairy-based
Correct answer: Gelato has less fat, less air (overrun), and is served at a warmer temperature than ice cream
Gelato typically has lower fat content (more milk, less cream), lower overrun (less air), and is served at a slightly warmer, softer consistency than American ice cream.
Question 2: What is 'overrun' in ice cream production?
- The amount of mix that overflows during freezing
- The percentage increase in volume due to air incorporated during churning (Correct answer)
- The excess sweetness from too much sugar
- The crystallization on the surface of ice cream
Correct answer: The percentage increase in volume due to air incorporated during churning
Overrun is the percentage volume increase from air whipped into ice cream during churning; premium ice cream typically has 25–50% overrun while commercial brands may reach 100%.
Question 3: What is the role of sugar in frozen desserts beyond sweetness?
- It only adds calories
- It lowers the freezing point, prevents large ice crystal formation, and contributes to texture (Correct answer)
- It speeds up freezing
- It prevents overrun
Correct answer: It lowers the freezing point, prevents large ice crystal formation, and contributes to texture
Sugar depresses the freezing point of the mix, which controls the final serving texture and prevents the formation of large, grainy ice crystals.
Question 4: What is sorbet, and how does it differ from sherbet?
- They are identical products with different regional names
- Sorbet contains no dairy; sherbet contains a small amount of milk or cream (Correct answer)
- Sorbet contains eggs; sherbet does not
- Sherbet is always fruit-based; sorbet can be any flavor
Correct answer: Sorbet contains no dairy; sherbet contains a small amount of milk or cream
Sorbet is dairy-free, made only from fruit purée or juice and sugar syrup, while sherbet (as defined in the US) contains a small amount of milk or cream.
Question 5: Why is an ice cream base pasteurized before churning?
- To improve flavor only
- To destroy harmful pathogens, especially since bases typically contain eggs and dairy (Correct answer)
- To increase the fat content
- To add more air before churning
Correct answer: To destroy harmful pathogens, especially since bases typically contain eggs and dairy
Pasteurization destroys pathogens such as Salmonella in the egg- and dairy-rich ice cream base, ensuring food safety.
Question 6: What is a 'parfait' in the context of classical frozen desserts?
- A layered sundae served in a tall glass
- A French frozen mousse made with pâte à bombe, whipped cream, and flavorings that does not require churning (Correct answer)
- A molded gelato dessert
- An ice cream served with fruit coulis
Correct answer: A French frozen mousse made with pâte à bombe, whipped cream, and flavorings that does not require churning
A classical parfait is a still-frozen (unchurned) dessert made by folding whipped cream into a pâte à bombe base, then freezing in a mold.
