My wife and I are working to learn authentic Indian cooking. We're fortunate to have a few Indian markets around us, so it's easy to find the right ingredients. If you've not been to one, the produce and spices are incredibly good, and cost but a tiny fraction of what they do in the supermarket.
Anyway, my wife has been trying a few recipes for butter chicken. One of her early attempts called for 3 t cayenne pepper. She misread and used 3T
It was awesome! Don't know why one would make it any other way.
