As the cumin sizzles add peppercorns and bayleaf.
Follow this up with the garlic, ginger and chopped onions.
As the onions turn translucent and start to slightly brown add the tomatoes.
Mix well and let them cook together for about 3-5 minutes.
Mix again and add the salt, turmeric,red chilli powder coriander powder, cumin powder and garam masala powder.
Mix well and lower the heat to a simmer and let this cook till the oil seperates and the tomatoes are broken down.
Mix well and cook down further till it becomes a paste-like consistency.
The buna masala is now ready.
