Instead of Fresh tamarind

Dried tamarind
Use the same weight, soak in hot water for 20 minutes, squeeze out the pulp, and strain. Closest to fresh.
Tamarind paste
Use 50% of the weight, add gradually, and taste. Concentrated and more sour.
Tamarind extract
Use 40% of the weight and add gradually; it is strong and already strained.
