Riddle

When in hot water I get harder. I am only useful once broken. Some people eat only the white part for its low fat, high protein nutritional content. What am I?

Choose an answer

A.A potato
B.A nut
C.A shell
D.An egg
Hint: It's a 2-word phrase with 5 letters, starting with "A".

Answer

An egg

Why this is the answer

Boiling an egg firms it up, it must be cracked open to be used, and the egg white alone is a popular low-fat, high-protein food.
