All good advice

If you cook a Plain Chicken Curry and then a Chicken Dupiaza
The difference is really only the Onion in the Dupiaza
Then if you cook a Chicken Tikka Chilli Masala, its a much more complex curry
and nothing like the Plain Chicken Curry taste.
A neutral base is the blank canvas.
Just keep experimenting with recipes and flavours.
