Just take your favorite Blonde ale...brew and ferment as usual. Take your chile, I prefer Anaheims, and roast it on the BBQ until the skin is nice and blistered. Put it into a plastic bag while still hot so it can "steam" then put it into the freezer overnight. Freezing the chile will burst the cell walls and let all the goodness out when it thaws. Place the frozen chile( skins, seeds, stem, everthing) in a carboy and rack the finished beer on top of it. Let it sit in the secondary until you are happy with the amount of flavor/heat. I find right around 5 days is good for Anaheims but it varies.
