An extremely hot red chili pepper sauce with slightly thick consistency and mild pungent color.

Chili sauce is a condiment prepared with chili peppers and sometimes red tomato as primary ingredients. Chili sauce may be hot, sweet or a combination thereof, and may differ from hot sauce in that many sweet or mild varieties exist, which is typically lacking in hot sauces. Several varieties of chili sauce include sugar in their preparation, such as sweet chili sauce and Thai sweet chili sauce, which adds sweetness to their flavor profile. Chili sauce may have a thicker texture and viscosity when compared to that of hot sauces.

Chili sauce can be used as a dipping sauce, cooking glaze and marinade. Sweet chili sauce is used in Thai cuisine, and is also sometimes used in the preparation of sushi.
