- Pressure cook the potatoes, green peas and cauliflower. Just add enough water to pressure cook. Do not discard the water. 
- Once cooled. Remove the excess water in a glass. 
- Mash the potatoes, green peas and cauliflower. The mashing should be as per requirement. I mash it completely. Some people like some pieces, or as called in Mumbai language, khada bhaji. 
- Puree the tomatoes, capsicum and green chilly in a blender 
- In a big pot or wok, add 2 tablespoon butter. 
- Once hot add the tomatoes, capsicum and green chilly puree. 
- Let it cook for at least 5-8 minutes on medium stirring in between. 
- Now add the mashed vegetables. 
- Add the Pav bhaji masala, turmeric powder, red chilly powder, salt and mix well. 
- Adjust the consistency by adding the water you removed from the bhaji. (The consistency depends on you, but generally, it is semi-thick). 
- Let it cook for 5 minutes on medium. 
- Reduce to slow, add 4 tablespoons of butter and let it simmer for 10-15 minutes. 
- While cooking, cover it with a lid, or you will have the bhaji splatter all over. 
- Garnish it with coriander and butter and serve hot with homemade Pav.
