Simmer for Flavor. Pour the chili sauce into a small pot or sauce pan. Heat and simmer for 10 minutes to let the flavors meld and develop. This is an important step. Taste and adjust for salt, honey, and other spices. Add more water for a thinner sauce. It's really meant to be a thicker sauce, and it will thicken up as it cools, but if you prefer a thinner sauce, go for it!
