I'm growing some chocolate habanero peppers this year and have been toying with the idea of making a coffee based hot sauce. I have a recipe that uses tomatoes for a smoother sauce, but I'm trying to figure out the beat way to get coffee flavor into the sauce. My first thought was espresso infused vinegar. Maybe running vinegar through a coffee or espresso maker. I've never done it nor can I find someone who has, so I'm not sure how much coffee flavor the vinegar would carry over, or how prominent it would be in the actual sauce.
Thoughts?
