if we DIDN'T HAVE enough apples, we couldn't bake an apple pie.
in this sentence, can we use "HAD NOT" instead of "didn't have"? Are they interchangeable?
You can use 'had not', but it's rather uncommon, and very seldom used in American English. When 'have' means 'must', 'drink', 'eat' or anything other than 'possess', 'do' is needed in negative forms and questions: Did you have an early breakfast? You don't have to do it.
