Cobek
A stone mortar and a pestle: sambal that is bruised, not pureed.
The journey
Indonesian sambal starts in a cobek — a wide, shallow stone — with an ulekan pestle. Chiles, shrimp paste, and tomato are crushed until they become a relish that still shows what it was. A blender makes a different food.
A Thai mortar is taller. The cobek is a plate with a memory.
In the kitchen
Toast the shrimp paste first. Add chile and salt. Work to a coarse paste. Taste for heat before you add more.
The Indonesian volume's sambals assume this stone. Serve the sambal in the cobek if the table is small.
