What are the available custom recipe icons?

UserBird

I spend a doubtfully lot of time in the icon lottery. Once I have developped the recipe and want to put it into production,

1. I go to fontawesome.io and find an icon I like
2. I put the name part, prefixed with `icon-`, in the json file
3. No hit.
4. No hit.
5. No hit.
6. Hit

What is the subset of icons available for recipes, it's time consuming to play this lottery...

Icons from fontawesome 3.2 should work
