Can the Prestidigitation cantrip flavor magical food?

Question

The prestidigitation cantrip's description lists the following effect as one option:

You chill, warm, or flavor up to 1 cubic foot of nonliving material for 1 hour.

The create food and water spell's description say:

The food is bland but nourishing, ...

My DM has established that goodberry also follows the same pattern with create food and water, they are bland. Then it occurred to us that we can use prestidigitation to flavor the food (and berry) created so that we can basically write off the need for rations when dungeon-delving.

Can prestidigitation flavor magical food?

Answer 1

Yes

The food made by create food and water isn't magical. It was made with magic, but the duration of the spell is instantaneous so it can't be dispelled or negated with an antimagic field. It's just ordinary, bland but nutritious food once it has been made.

Goodberries on the other hand are magical, however prestidigitation states that it works on nonliving material. It doesn't say anything about nonmagical. As such it will work fine.

I don't see why you are worried about the flavor though. The food and water created by the create food and water spell is bland, but nutritious. Each casting can keep at least 30 people fed and watered per day. Unless you DM is introducing some kind of house rules that will be enough to keep the party going. I've only ever had one DM take note of rations anyway.
