Kerala style Mushroom Roast – Koon Ularthiyathu

Today my lunch was Rice, Moong dal curry and Kerala style Mushroom roast. After coming to Muscat I had many chances to taste Kerala food either from Kerala hotels or home made Kerala food from our neighbours. There are plenty of Kerala hotels here. There are a variety of dishes in Kerala cuisine. I also love their style of biryani served with citron pickle, raita and papad. I love this combo a lot. Though people at our home don’t love Kerala style biryani a lot. I love it. Ularthiyathu or roast in Kerala is made usually with non-veg. During my last vacation I got a Malabar cuisine cookbook there was a recipe of erachi ularthiyathu and I adapted the recipe for making it with Mushrooms. It was so tasty and it went well with Rice and dal. The coconut slices added gives an excellent taste to the dish. Let’s get into the recipe of the mushroom roast. Also, take a look at my other mushroom recipes.
