I made Griffin's Pulled Beef on Sunday. It was pretty tasty, but I noticed that one of my chuck roasts was considerably drier than the other. The meat came in a two pack from Costco. One chuck roast was 2.5 pounds and the other was 1.5 pounds.
The 2.5 pound roast finished in 7 hours 30 minutes and the 1.5 pound roast finished in 7 hours and 45 minutes. Both were prepped and cooked in a similar manner. After cooking, I let them both rest 30 minutes before pulling them. The smaller one turned out much more tender and moist.
Any ideas why that might happen?
