is starfruit cake and chili frost crab soup good only for 100% cooking mastery?

And here I am only eating apples, I have nothing I need to plant so I just keep doing apple seeds and have millions to try and eat.

In my limited knowledge the food doesn't matter, as long as you don't run out. So for me I do not have to waste time cooking and just keep farming.

Towns directly exchange for food boxes, eat whatever is abundant.
