No beans to spill at the moment, Rob. Just trying to replicate said dish from local TA.
This one was closer than the last using blended tomatoes, finely chopped onions and green chillies, a few ladles of base, salt, tandoori masala, methi, coriander, mango chutney and a pinch of sugar.
It was really nice, and, if you're interested, I'll post details when I can.
