What is the process of tempering chocolate called?

  1. Conching

  2. Blooming

  3. Crystallization

  4. Emulsification


Correct Option: C

What is the chemical reaction that occurs when sugar is heated in the presence of an acid?

  1. Caramelization

  2. Maillard reaction

  3. Glycation

  4. Hydrolysis


Correct Option: A
Explanation:
