I just posted a buttermilk jalapeno cornbread recipe that's exactly what I was looking for. It's moist, tender, and while not completely crumb-free, it's close. The slightly sweet batter is perfect with the mildly spicy peppers. This is a great cornbread recipe, and was even better spread with a touch of honey and lime butter. If you're not into jalapeno, just leave them out and you'll still have a great plain cornbread.
