To begin making the Goan Style Mushroom Vindaloo, first prep all the ingredients, and get all the spices together.
The next step is to roast the masala for the vindaloo.
Heat a small skillet over medium heat; add all the ingredients to be ground into a paste and roast them for a few minutes until you get a roasted aroma and the red chilies are lightly crisp.
Turn off the heat, allow it to cool a bit and grind into a fine powder.
Pound the ginger and garlic in a pestle and motor and keep aside.
Heat oil in a pan; add the ginger garlic paste and saute for a few seconds. Add the chopped onions and saute until the onions are tender.
Add the turmeric powder, the ground spice powder, the mushrooms. Add the salt, cover the pan and simmer for 10 minutes until the mushrooms are cooked.
Once done, open the pan, and allow the vindaloo masala to thicken, but evaporating any excess liquid. Turn off the heat and serve warm.
Serve the Goan Style Mushroom Vindaloo along with steamed rice or even lachha paratha for lunch.
