Chestnut flour expired. Can I still use it?
Several years ago I bought chestnut flour, meaning to make castagnaccio. I never did, and last night I came across the flour, two years beyond its expiration date!
I'm assuming I should just toss it but wanted to check to see if it could be use-able. It wasn't easy for me to find, and it was expensive. I've never baked with it before and don't know how resilient the flour is.
