Spicy chili can be cooled down by adding more ingredients. Adding more beans, water or meat can help disperse the spiciness through out the dish.
If too much pepper is added to chili or soup, there are a few ways to cool it down and save the recipe. Adding a dash of sugar is one way to cut the spiciness. Keep adding small amounts of sugar, tasting the chili after each addition until it is suitable to taste. Serving the dish with a dairy product will also cut the heat. Sour cream, yogurt or ranch dressing make great garnishes that will tone the food down.
