I've been known to go heavy on the heat myself (but sometimes ok w/me!). Have tried many options to turn down the heat for the woosies, depending on the dish flavors; but usually more broth/liquid usually does the trick and other non-heat spices will do or more veggies. Just made a great Moroccan Beef stew which called for habenero, and cayenne, and bunch of other great spices. Turned out tasting great BUT some thought it too hot...SO I added more beef broth and some orange marmalade. Have to say its fantastic now! It even improved the flavor of my stew!! Really blended all the flavors nicely. So, really no set rule, just be creative to the flavors of your dish! ~ Bon appetet!
