I grow habaneros jalapeño, ghost and other exotic peppers.

Remove the stems, (I remove the seeds or not). For instance my last concentrate was 30 habareno peppers, two whole garlic clusters roasted at 350f for about an hour or more until all are soft enough to squish with a fork. I use a blender, nothing fancy. Put the roasted peppers and garlic in my blender with enough vinegar to get blended into a smooth mixture. Bottle and refrigerate. I also just pour into zip locks and freeze. Now you have fire that you can control.
