Use Hulled barley since Pearl barley is just equivalent to Rice
If you are buying whole hulled barley, just break them into barley rava in food processor. Soak this overnight. 1 cup of barley requires 2 cups of water.
How to make pongal
Cook soaked barley with an additional cup of water and salt. Use the water that was used for soaking as well. I use rice cooker to cook barley.
Oil - 1 Tbsp
Mustard - 1 tsp
Red chillies - 2
Urad dal - 2 tsp
Hing or Asofoedita
Tamarind pulp - 4 Tbsp (soak half lemon size tamarind in hot water and take pulp)
Add tamarind pulp and turmeric to Tadka. Let it boil fow mins. Add this to the barley.
Once barley gets cooked well, let it to cool for sometimes. It will be sticky initially. Once cooled, seperate them using fork. Once seperated, it does not becomes mushy even when you warm it again.
Variations: Lemon can be used instead of Tamarind
