substitute chili paste recipe

Since this thread came up again, keep in mind that chili powder (despite name) isn't very hot. It's really a warm spice blend, usually including cumin and oregano, sometimes other flavors like garlic.
So, if no chili paste on hand, go for the items susan g & Patricia Jones suggest. Or even fresh chilis (they keep well in the freezer).

Chili paste is best for any recipes. It adds heat and spiciness to the food items. But, if you want to substitute chili paste, you can try - Crushed Red Pepper Flakes, Hot Sauce, Ketchup With Pepper.
