Start with preparing garlic-chilli paste. For this, you'll need mortar and pestle.
Roughly chop garlics and chilli; then add into mortar and pestle along with little salt.
Crush everything together until rough paste is formed.
In a mixing bowl, add gram flour, turmeric powder and garlic-chilli paste.
Gently mix together and then add around 1 cup of water. Combine everything until lump-free mixture is formed.
Next, heat a pan over high heat and add oil into it.
Once oil is hot; add mustard and cumin seeds. Let them sizzle for few seconds.
Turn heat to medium and add asafoetida into the pan. Next add curry leaves and gently combine everything.
Tip-in chopped onions into it and season with salt.
Stir for few minutes or until onions are softened.
Once onions are softened, turn heat to low and slowly add gram flour mixture into the pan.
This mixture immediately starts to thicken, so gently add water into the pan while stirring continuously.
Add around 2-3 cups of water and stir continuously.
Turn heat to medium and allow it to cook for another 10-15 minutes or until gram flour is cooked.
Cook until raw taste of gram flour goes off; if required add more water while cooking.
Gram flour mixture will starts to thicken. It should be thoroughly cooked in another 15-20 minutes.
Test taste and adjust salt if required. Simmer it for another 5 minutes.
Finally add finely chopped coriander leaves and mix it together.
Pithla is ready; serve it with hot bhakri, chapati or rice and some sliced onions, lime on sides.
