Unfortunately I didn't take any pictures, as I wasn't expecting it.... but I believe I've made my closest BIR replica yet.
On the Madras, as I think I posted before somewhere, since the Ashoka base (and associated recipes) came out, I felt I was getting further from BIR instead of closer. There was too much salt, too much garlic, and I was using too much bunjara. Tonight I went back to basics. I used the BE Madras recipe (very simple), with the following changes: 0.5 tsp g/g paste, Ashoka marinated chicken, Ashoka base, and 1 tbsp of (salt-reduced) bunjara. Everything else was as per BE. This was the closest BIR Madras I've ever done.
As an added bonus, I also made my best ever naan. I used the idea that came up on the forum of using a pizza stone. I preheated the stone in the oven to the maximum - 600 degrees fahrenheit in my case. I used UB's naan recipe, with an added dollop of yogourt. The results were BY FAR the best naan I've made: big and fluffy with crispy bits here and there. They cooked in about a minute. They also were cooked through, which is a problem I've had on the hob: if the tava is too hot they start to burn without properly cooking through at the edges. I HIGHLY RECOMMEND this method!
