Instead of Dried green mango

Dried mango powder
Use the same weight, add early with the spices. Same dried-mango sourness but disperses and colours the dish more evenly.
Raw green mango
Use about 3 times the weight, grated, and simmer a little longer. Fresher, juicier sourness; adjust salt and sugar.
Tamarind
Use about 50% of the weight, soaked and extracted. Fruity sourness rather than dry mango tartness.
