Lots of curry recipe books can be quite fiddly. This is practical and easy to use. There are a few ingredients that can be hard to get, which is why it gets four and not five stars from me. I'm lucky in that I live near a vibrant Asian community and was able to source a lot of the stuff, but there are some things you will not find in regular supermarkets. The other thing I would be slightly wary of is spiciness levels. I made the Andrha chilli chicken the other day. It recommended two fresh chillis and five dried chillis. I thought this was a bit much, even for a spicy dish. I added two fresh chillis and it was more than enough for us. I suggest adding your chilli amounts gradually to taste.
Having said all that these are great recipes which I have used time and time again. We use them at the times when we're doing Slimming World, and during regular times as well, they taste so good. They are very adaptable and on the days when I want to be syn free on Slimming World I will substitute the meat element for Quorn.
Using this recipe book was the first time I had tried making samosas or bhajis and both went really well and were much easier than I expected. There is a great selection of veggie dishes, and even soups.
