Thai Sweet Chilli Sauce is a popular condiment in Thai cuisine that is known for its sweet and tangy flavor with a mild to moderate level of spiciness. It is typically made from a combination of red chili peppers, sugar, vinegar, and garlic, and is often used as a dipping sauce for appetizers, such as spring rolls and chicken wings. The sauce can also be used as a glaze for meats, a marinade, or a dressing for salads.
