Sambal Oelek
Java and Bali, Indonesia (pan-archipelago tradition)
Sambal oelek is Indonesia's master hot sauce and the mother preparation from which dozens of sambal variations are derived: crushed fresh red chillis with salt and optionally a small amount of lime juice, made in a stone mortar (cobek) with a stone pestle (ulekan — from which the name 'oelek' derives). It is a condiment, a cooking paste, and a building block simultaneously. Unlike cooked sambals, sambal oelek is raw — the vibrant, aggressive heat of fresh chilli is uncomplicated by caramelisation or frying and strikes the palate immediately and cleanly. The mortar-and-pestle technique (rather than a blender) creates a slightly chunky, uneven texture that releases volatile capsaicin and aromatic compounds at different rates as you eat — blended sambal is homogeneous and lacks this dynamic.
