I went to one of the local supermarket chains around here I don't usually go to, Schnucks, and bought a package of their store-brand brats, a jalapeno and cheese option. Their ingredients were pretty pure, I felt the price point was good, and yes indeed, the brats came out great. For me they were not too spicy, but any time you are dealing with fresh pepper their heat can vary. Will buy again! While typically out of the way for me, now that I am seeing my chiropractor, that is just around the corner on a weekly trip.
I par boil mine for about 7 minutes in the microwave, then put them on the grill for a nice char and finish cooking.
Schnuck's is a chain based out of the St Louis, MO area. They carry a bunch of "ooey gooey butter cakes'" which is a regional treat I had never encountered on the west coast. Being low carb I should not get too introduced...
