I've just started using Evernote as a recipe book as well. I already had one online with a Dutch service, but it required typing out recipes I found elsewhere on the web or in cookbooks, and I was just tired of doing that. My collection of magazines and ripped-out recipes is slowly shrinking as I find the recipes online and clip them. I don't mind the recipes looking different, as long as there is not too much ***** surrounding it (EN Clearly sometimes takes away valuable information, so I have to clip the entire article).
I have 121 recipes in my cookbook-notebook now (which is nothing compared to others, but hey, I'm just starting ). My tags include course (main, dessert etc), way of cooking (oven etc.), type of meal (salad or soup for example, but also vegetarian, pasta or rice). I'm also adding a quick or slow tag. Other than pasta and rice, I do not tag main ingredients because they are in the ingredient list already, so I can quite easily find them. Perhaps I'll regret that later, when I have more recipes, but I can always go back and change my tagging (I'm ignoring the fact that it would take a lot of time).
Oh, and I might split my cookbook in two for recipes to try and recipes we already love. Or I might start using tags for that as well.
I am planning to make weekly meal plans using note links. I have a separate grocery list in EN that I keep updating, so I can have the mealplan on the computer and the grocery list on my phone and easily add stuff. Or just copy-paste.
