Do you capitalize f in french bread?

Generally, you don't capitalize "french" in "french bread." This is because "french" is acting as an adjective describing the bread.

However, there are a couple of exceptions:

* If "French" is part of a proper noun: For example, if you are referring to a specific bakery called "The French Bread Company", you would capitalize "French."

* If "French" is used at the beginning of a sentence: You would capitalize it in this case, as you would with any other word.

So, the answer is: usually no, but there are some exceptions.
