What advantage does using liquid nitrogen have over the traditional method?
What advantage does using liquid nitrogen have over the traditional method?
- Faster freezing and smaller crystal grains (correct)
- Faster freezing and larger crystal grains
- Slower freezing and larger crystal grains
- Same freezing speed and smaller crystal grains
What is the downside of using liquid nitrogen to prepare ice-cream?
What is the downside of using liquid nitrogen to prepare ice-cream?
- Ice-crystals remain small and doesn't require specific storage temperatures
- Ice-crystals grow slower and requires warmer storage temperatures

Study Notes
Methods of Making Ice-Cream
- Two methods of making ice-cream are mentioned: traditional method and using liquid nitrogen
- The traditional method is not specified, but it is implied to be the conventional method of churning cream and sugar
Advantages of Using Liquid Nitrogen
- Using liquid nitrogen has the advantage of rapid freezing, allowing for instant creation of ice-cream
Disadvantages of Using Liquid Nitrogen
- The downside of using liquid nitrogen is that it requires specialized equipment and handling
Texture of Ice-Cream Made with Liquid Nitrogen
- The texture of ice-cream made with liquid nitrogen is distinguished by its smoothness and lack of ice crystals, resulting in a more even consistency
