Short reviews of recipe books:
50 Great Curries of India
These all taste delicious, but are lots of work. I use a lot less chilli. They are all better with fresh, whole spices (as suggested), provided you have some kind of spice mill / food processor; if you don't, just use pre-ground, it's not worth the effort! Each recipe has a mix of half a dozen or more spices, so you'll need a large collection.
Cakes, Pastries and Bread - Jennie Reekie - Marks and Spencer 1977
I only actually make half a dozen recipes from this book, but they all turn out pretty well. I should branch out more, but I bake infrequently enough that I want to make my favourites again when I get round to it. Ingredients in both metric and imperial, so you can choose your preferred system.
20 minute suppers - Itsu
I really like this book. It doesn't require lots of exotic ingredients, and suggests substitutes for if you're not near a large supermarket; the recipes work just fine with quite a lot of variation. All the meals are a good blend of simple but tasty. There's a lot of variety in terms of meat/fish/eggs/tofu, vegetables, staples, and spices, and mix-and-match is encouraged.
I think this is the recipe book where I've had the highest success of "I'd like to try that" and "I'd like to eat that again"; usually less than half the book is that attractive.
Downside: as with all 20-minute-meals, it's more like 30; veg prep is hidden in the ingredients list, as though we all have pre-chopped spring onions to hand. But it's genuinely simple, and you could do the veg prep in the morning if you literally only have 20 minutes to cook dinner later.
Fresh India - Meera Sodha - Fig Tree 2016
This is a fusion cookbook - vegetarian Indian meals, aimed at a British audience, using seasonal British vegetables and not too much chilli. Recipes are ordered by type (root veg, greens, aubergines, salads, breads, chutneys, puddings, drinks); there are also alternative contents by type of meal (midweek / for the freezer / etc) and by season. The recipes are not quick, and as with Indian cooking in general, many require preparation of several different dishes. Each recipes lists whether it is a whole or part meal, and what other dishes complement it. The bread section is extensive, and includes several types I've not come across, or have only had in restaurants; many are pan breads, and easy to fry-up for a snack! The lassis are delicious.
The most consistently good recipe website I've ever come across. Never had a dud from there.
