Cooking for small group

13 lbs raw butts - Two large ones
3 to 4 racks of spares
1 each half pan full of beans, slaw and potato salad

That will be plenty for 25

I'm no expert but I would prefer to cook 2 larger (9-10ish lb.) butts rather than 4 smaller ones if you can find them. I think the come out more moist. How many ribs do you think each person will eat. If an average rack has 12 bones x4 that's 48 bones. So you'll have a little less than two per person. If you think everyone will only eat 2 then you should be fine with 2 large butts, 4 racks and your 2 pans of sides. If it's me i'd make 5 or 6 racks because I always freak out about running out of food. Drives my wife nuts but keeps the people happy. Again i'm no expert.

I agree with the others on the butts and the sides. I kind of agree with fingerlickin on the ribs, but I always make too much food for the same reason he states. But ribs make good left overs!

Can you get me on the guest list? Sounds like some good chow!

Depends on your goal I guess if you plan on having plenty of ribs for everyone to eat the amount of ribs they wat you better figure 7 to 10 racks. But a 4oz sammie and 2 to 3 ribs is a nice meal. I don't doubt that if you cooked 10 rack it would all get eaten but you will end up with left over pulled pork but that ain't too bad either
