From The Best Recipes in the World by Mark Bittman. "You can make this easy mint chutney quite hot, and it still seems balanced, especially when served with a rich, flavorful meat like lamb. Heat comes in a wide variety of flavors, and what works best here is a bit of roasted fresh hananero (also called Scotch bonnet), the hottest chile you can find. But minced raw jalapeno or hot red pepper flakes are also good. No matter what you use, add a little at a time (I'd start with a quarter teaspoon if you're using habanero) and taste repeatedly, bearing in mind that the heat of chiles can "bloom" after a few minutes. Serve this with a neutral dish like plain rice, and perhaps a cooling salad."
