I just bought my first batch of fresh green beans. I bought a pound. I found that I need to wash and pull off the ends to prep before I cook. Ok, easy enough. My question is, can I do this all at once for the whole pound, even though I won't cook it all at once? Or is it better to wash and cut as I need them for meals? If I can do the whole pound, how do I store them? Right now they are just in the veggie bag from the store. I'm new at fresh food prep, storage, and cooking, lol! Hopefully some of ya'll have more experience!
