I only buy brats from Hyvee and Fareway. I usually just throw them right on the grill. If I want beer flavored ones I just buy them instead of messing with the boiling in beer. I might have to try some of these techniques though.
I only get them from the meat counter at HyVee. Every other kind of meat I get at Fareway.
I haven't had any explosions or flareups since I started poking them before I boil. I boil them in beer since the only other alternative is water and I think that takes some flavor away. I've been thinking lately about trying to boil them in Coke. I haven't heard of anyone doing that, but I think the flavor it adds would taste good.
So far, I haven't wanted to risk ruining a brat.
