The peel is used in Karnataka for making curry. It has several other uses too, you can use it in your homemade face packs, use it to clean your teeth, remove the odors from your sink..but try this recipe if you like bittersweet :-)
1 cup peel chopped
1 cup water
Boil together for 15 mins or so on simmered gas. Strain. Don't throw away the strained liquid, you can use it as a conditioner for final rinse on your hair!
Add half cup sugar or 3/4 cup honey
2 cloves full or powdered
1 tbsp water
Boil, simmer till sugar or honey caramelizes. Remove from heat. Let cool and serve with rusk/toast. We enjoyed this with parathas.
