Lets take chopped onion, ginger, garlic, green chilli, red chilli powder, cumin powder, garam masala and now grind it and make a paste.

Now, let's take a pan, add the ghee in it. Once the ghee is hot, add some chopped green chilli, saute for a while then add prepared onion paste and saute again for it to 2-3 mins.

Now add the tomato puree and saute at least 4-5 mins. Now the tomato puree is dried out. Now add the fresh cream in it and mix it well. next, add some water and let this gravy boil for 2 mins. Now add some coriander leaves, salt to taste and mix it well. Now gravy is ready and keep it aside.

Lets take another pan and add some butter to it. Once the butter is melted, add chopped capsicums, sliced mushroom's and let it cook for 2 to 3 mins. Now the mushrooms and capsicums are nicely cooked and add these into another pan in which the gravy is prepared, mix it well and cook it for another 2 more mins. Now Mushroom Butter Masala is ready to plate, garnish it with the green coriander leaves and serve it hot :)
