Sweet chili, more often called sweet chili sauce, is a Thai-style condiment that balances the heat of chili peppers with sugar or another sweetener, plus vinegar or lime juice for tang. It likely originated in Thailand, where a similar sauce is served with grilled or fried chicken, and versions are now made across Southeast Asia with local variations in chili type and sweetener (palm sugar, brown sugar). It's used as a dipping sauce for spring rolls, satay, and fried foods, and as a glaze or marinade for meat, poultry, and fish.
