I followed this recipe exactly except for adding red bell peppers. Well, this is unlike any tikka masala I have ever tasted. The garam masala was so overpowering and the only flavor that could be tasted. I wound up not even finishing a serving and throwing out the whole batch.
If you like Indian food, you will like this recipe. Shrimp Masala is my favorite, so I was very excited to find this recipe. I didn't have ginger, and only cooked the onions for 10 minutes. I also used low fat yogurt, it tasted very similar to our local restaurant.
