Here's a recipe that I use:

Buffalo Chicken Wings

2 1/2# chicken wings
1/2 cup cayenne pepper sauce
1/4 cup butter, melted
2 Tblsp worcestershire sauce

Split wings at joints and discard tips; pat dry. Bake wings on a rack in a roasting pan at 425 for 1 hour; turn halfway through cooking time. Combine remaining ingredients. Toss wings in sauce to coat completely. You can also use purchased wing sauce.

I would plan on 3-6 wings per person. I know that I can eat 10-12 at a time, but I eat less if there's other food.

Hope this helps!
