souring agent
Worcestershire sauce
5 g1 teaspoon
16 g1 tablespoon
Density ~1.1 g/ml; 4.93 ml teaspoon ≈ 5.4 g; traditional sauce contains anchovy.
Instead of Worcestershire sauce
Soy sauceUse the same weight; it is saltier, so reduce added salt and taste before finishing.
VinegarUse 60–70% of the weight; it is sharper, so add a pinch of sugar to soften it.
Tamarind extractUse 50% of the weight; it gives sourness but not the same savoury depth, so adjust salt and sugar.
