I love massaman curry as it is considering as a very mild Thai curry. I ate it when I was very young. So I could taste some spice by being a Thai kid. When I grew up I found the fact that Massaman curry is very interesting.
Penang curry is generally milder than other Thai curries, however there are still common Thai traditional ingredients shared between them such as chili peppers, galangal and lemon grass, The key ingredient which gives this dish a distinctive flavour is the garnishing of finely sliced Kaffir lime leaf , it imparts a rich and aromatic flavour not comparable to anything else.
