A common dessert technique is _________.

flash freezing
gradual thawing
rapid rising
slow roasting

... During flash freezing, the outside of the dessert freezes quickly and becomes crunchy while the center cools yet remains liquid.

next

Question 7 of 20

Which of the following is sometimes used for flash freezing?

dry ice
high fructose corn syrup
liquid nitrogen
sodium nitrate

... Liquid nitrogen flash freezes at the low temperature of -321 degrees Fahrenheit (-196 degrees Celsius), but it is difficult to work with and hazardous if it touches exposed skin.

Question 8 of 20

Which tool traditionally associated with the medical field is commonly used in molecular gastronomy?

clamp
probe
retractor

Question 9 of 20

Knowledge of molecular gastronomy can help out in any kitchen: To prevent pasta from sticking together, add _____ to the water.

baking soda
lemon juice
oil
