Once you have lit the barbecue place the litti on it.
Roast it all over, turning frequently until done.
Remove on a cloth and dust off any ash from charcoal.
Soak the warm littis in ghee for 5 minutes and serve with chokha.
For Choka
Take the eggplant and make a few slits in it.
Add 2-3 cloves of garlic, one in each slit.
Now roast the eggplant, tomatoes and potatoes on charcoal.
One can bake or microwave it too. To give it a smoky effect place a bit of burnt charcoal in it. Check my post on baingan bharta to give this effect.
Roast the veggies all over until soft and cooked properly.
Remove and let the veggies cool down. Now peel the veggies and chop them roughly.
Add all them in a bowl, add chopped onion, coriander leaves, ginger, garlic, green chili, salt and mustard oil.
Mix everything with hand or a masher. Serve it with Litti.
