First, let’s bury the old myth. You do not need to thaw a brat before cooking it. In fact, starting from frozen can sometimes lock in moisture better. The key is understanding that patience, not speed, is your best friend here.
Frozen brats have a higher water content than fresh ones. If you blast them with high heat, the casing will burst, and your meaty dream becomes a shriveled, dry tragedy. We want a juicy, snappy sausage, not a hockey puck.
