This is a rich, aromatic Thai-style black pepper sauce packaged in a glass bottle. It is a savory, slightly sweet, and peppery sauce made from crushed black peppercorns, garlic, soy sauce, oyster sauce (or vegetarian alternative), sugar, and spices. Used for stir-fries (especially black pepper beef or seafood), marinades, or as a dipping sauce. Glass preserves the bold pepper aroma.
