Large chillies or small peppers

I bought loads of these at the farm shop this morning, I don't know if they are hot or just peppers. I plan to 'stew' them in a rediculous amount of olive oil, with tons of garlic & the odd caper. I suppose then we'll find out. They looked so nice that I went straight to painting and didn't study this morning... guilt overload.

Lousy photo, but there's no way I'm going outside again.
