How should I store my prepared potatoes?

Q:

I made a mashed potato and sardine mix for something similar to the croquettes on your recipe website. Should I store this mixture at room temperature, in the fridge, or in the freezer?

A:

The strong flavor of sardines would overpower the potatoes if combined and left out at room temperature for very long, which isn’t recommended from a food safety standpoint. You should keep food cold or keep warm until serving. If mixing together, I would suggest freezing the mixture until ready to heat up in the oven or fryer.
