How does food define someone and their culture?

(I'd prefer the answer to be 3-5 sentences long)

The spices, or ingredients, put into certain cultures food can define someone. Every culture has a different way of making the same meal. The way someone makes a meal can be one way it defines them and their culture.

The ingredients you used to make the food will be different from someone else. It shows you culture for example muslim eats samosas but some other people eats dosa, etc.
