If I use dried beans as pie weights and put them in the oven, can I save the beans and cook them later for eating?

Of course ceramic pie weights are not expensive and will last longer than beans.

I have one jar of dried beans that are dedicated pie weights. After baking once, I doubt you would want to eat them since they wouldn't rehydrate & cook properly.

I'm with Sam1148 - pennies work great, transfer the heat better than beans, and are reusable. Don't eat the beans after you use them as pie weights

I don't use any weights. I dock.

I agree with pantry shelf. You can continue to bake with them multiple times.

No. Use foil and coins, they have more weight and you can use them again and again.

I'm going to jump in there and say don't eat them. I have a jar of beans that I use for baking. After they have been baked, I return them to the jar for the next time I need baking beans. I have not tried to bake with them, but they look a bit toasted and I'm guessing they might not soften up properly.
