I would really encourage you to develop your own recipe book, using a recipe app. I use Recipe Gallery, but there are many other options. It is a great tool for collating recipes you like from different chefs, cuisines, sources etc. For instance I have recipes from BBC good food, Guardian recipes (Ottolenghi and others), Times guest chefs (I’m a subscriber), and various regional cuisines from Myrecipe and local equivalent worldwide (I need Indian, Canadian, Middle Eastern, vegan recipes in my life).
You can use the app to make your own notes, eg. Cooking time in your own oven, or specific spice mix you like, and also to capture recipes sent by friends and family.
I’ve used it for two years and it has really expanded my confidence, horizons and I can now look back at hundreds of dishes I’ve tried. It’s fab!
If you’re only looking for cook books, then I’d say:
-Nigel Slater, Real Fast Food
-Nigella Lawson, How to eat
-Simon Hopkinson, The Good Cook
-Jamie Oliver, any of his books if you need a confidence boost to get started, and
-Sami Nosrat’s Salt Fat Acid Heat to really understand the science of cooking in a fun, unpretentious way.
My next cook book will be the one of the Tray Bake ones, such a simple, genius idea.
