What's a good substitute for amchur powder? I want to make paneer in spinach + fresh fenugreek sauce, but I have no amchur. Many thanks ;o)

The sumac question is excellent, AntoniaJames. I feel that its sourness would be too different from the amchur sourness, but I can't quite put my finger on why that is. Yet I am certain it is true. The amchur, maybe, has that raw fruitiness, whereas sumac, in my mind, has a more salty characteristic. But who knows... What did you try?

anardana powder (dried pomegranate powder), or even blended up fresh raw green mangoes. Tamarind paste can be a tad too strong (in dire circumstances, I've fallen back on tamarind coupled with brown sugar to offset the pucker inducing tartness)

Thanks, nogaga!! Wondering if perhaps sumac would work . . . or maybe tamarind? ;o)

I'm sure Panfusine will have a better answer, but I've used ground dried lemon rinds and it has not caused any harm! It puckers less than real amchur, but it works.
