An easy, quick and no mess way to brown something is to blowtorch it. I love bratwurst, it just doesn’t look right not browned. I buy the pre-cooked kind. I put them in a zip-lock bag with some water in it and drop them in a pan of hot water for a few min and then pull them out and hold them with tongs and run the blowtorch over them. No mess, they look right, taste right and it makes no mess to speak of. The pan only has to have the water dumped out, I use that water to clean the tongs off. It also works for hotdogs, I’m sure it will work for other meat.
