We boiled 2 sacks Sunday and had a few extra so we peeled them, how long are they good in the fridge? When do I need to freeze? We were wanting to make a Crawfish Étouffée or something...

I would say no more than one week In fridge before freezing. If you can, vacuum pack them. Do not freeze in water. With that said, if they are not vacuum packed, they are only good for like 6 months or so once froze.

id say boil some garlic, onions, corn, and potatoes then use that and your tails for corn/crawfish bisque.. we usually add all the other leftover sides to it also (turkey neck meat, meatballs, shrooms, celery)

I leave the tails on and freeze them like that, it's a little more work when you defrost them but leaving the shells on helps them in the freezer last longer.

They are never the same in gumbo or chowder. Use them for like a Monica or some kind of pasta.

Spinach and crawfish omelet

Crawfish Monica type pasta dish is the shit with leftover tails.

We always boil an extra sack of potatoes at the end , take leftover tail meat and potatoes and make a crawfish potatoe salad , it has a good flavor and it's a little different color than normal with the seasoning . Good though
