So, the local supermarket had some 3.5# butts and an 8# brisket...a full brisket..not the flat. Trimmed it's about 12 pounds of meat. After doing a 16# brisket this one looks almost comically small, but we'll see how it goes. I also left the butts stay in the fridge rubbed for about 36 hours--started planning too far ahead. I rinsed them, soaked in cold water, re-rubbed minus the salt, and put them on. Will be interesting to see how it turns out!
