When listing out ingredients do you capitalize them?

In general, it is not necessary to capitalize the names of ingredients in a list unless they are proper nouns or the first word of the list. For example:

Ingredients:

- flour

- sugar

- eggs

- butter

- vanilla extract

In this list, only "vanilla extract" is capitalized because it is a proper noun.

However, if the list is part of a larger text, it may be appropriate to capitalize all of the ingredients to make them stand out. For example:

Ingredients:

FLOUR

SUGAR

EGGS

BUTTER

VANILLA EXTRACT

In this case, the all-capital letters help to distinguish the ingredients from the rest of the text.

Ultimately, the decision of whether or not to capitalize ingredients is a matter of style.
