Recently purchased raw brats that were frozen from our local meat market. I did thaw the brats out. I usually cook the brats on a charcoal grill. I needed to cook about 40 brats for a picnic, so I thought I would cook the brats onmy electric smoker. I cooked the brats on the smoker until the internal temp was 160. This took about 2 hours at a temp of 235. They never turned the cherry red color that most recipes said. The end result was brats that were a little hard and not juicy at all. I did put a light coating of Olive oil on the brats before going in the smoker. What did I do wrong? They are always juicy when I cook them on the grill. Note: The skins weren't busted open.
