I just buy those things from Smiths that are like a plastic wallet book, A4 size - ie: you open it up like a book and there are plastic pages to slot things in - a display book I think they might be called.
I do an alphabetical list, of headings such as "Pastry - Puff, Pastry - Shortcrust, Pork" etc and leave huge gaps under, to write in the page no and recipe title. In the sweet bit, I put them under "Glass dish puddings, frozen puddings etc".
Mostly works! It gets round the odd savoury recipe which lurks on the back of a pudding page too.
Only in my ipod. In my head I'm all nice and organised, in reality I am a complete nightmare. I think I've done the storing of recipes in a ring binder before, but they all got forgotten, as they weren't sorted.
I have one of these which has section dividers (meat, fish, dessert, baking, etc) and plastic wallets for cut-out recipes. I copy out my tried and tested recipes and then keep the clippings until they have passed the taste/competency test and then copy them in.
It was my birthday present this year! I like it because you can buy extra pages and wallets; I used to have a notebook that I stuck stuff into but I hated not being able to find recipes by type - I had to remember when I stuck them in. Go for it!
