I just finished my first batch of this base, having made a range of dishes from it.
Not my favourite so far, I must admit. I think it has too much in it, and doesn't leave enough to the final cooking. Tinned tomatoes are a no-no for me from now on, you can taste them in all the dishes, and the use of chilli / mirch in my opinion should mostly be left until the final cook too. Oh and the potato didn't really add anything as far as I can tell.
Nice, but not as good as my first batch of BE, which is narrowly winning over CA's sauce.
