Whether you make them yourself or use some premixed rubbish, some orange zest grated into the batter is awesome for both sweet and savoury pancakes/crepes.
I know for sure because I ate them for the past two nights with everything from spinach to ham to chicken curry to chocolate to amaretto (on fire

) to lemon to avocado to etc, etc.
Hmm. Didn't realise until I typed it just how many crepes I ate in 48hrs.
