I enjoy making sourdough, but I don't want to make it every week. I would like to make it maybe once a month if that. I don't like the hassle of feeding a starter constantly, it doesn't feel worth it when I'm only making sourdough every once in a while.

Is there an alternative to maintaining a starter? I've tried throwing the starter in the fridge but I'm so lazy it just becomes a little cup of mold by the time I take it out two months later.

Many thanks for your wisdom oh Bread Lemmies.
