This's the stuff you get with various appetizers in Indian restaurants, such as the starter pappadams. This is also great with samosas. Or dhoklas. I make this often.
I used food.com for most of this recipe:
1 cup tamarind paste (Laxmi brand, Indian grocery stores)
1 cup dates, pitted (or apple butter, to save time)
4 cups water
1 teaspoon red chili powder
1 teaspoon cumin powder
1 teaspoon ginger powder
2 teaspoon salt
1.5 cups jaggery (unprocessed sugar - best in Indian grocery stores) or 1.5 cup brown sugar or 1.5 cup sugar
Boil the water and add the dates and jaggery to it.
Blend and transfer back to cook pot
Add tamarind paste and seasoning and bring to boil
Shelf life : 2 weeks
