I have a preference for those recipes that make full use of the Thermomix’s multiple abilities. I have developed this flan recipe for like-minded Bimby fans who seek out opportunities to play with the machine and maximize its potential. See how many times you can use your Thermomix while preparing this Onion Flan recipe AND the ingredients that comprise it!

note about milling flour: Instead of milling your own flour, you can simply begin with an equal amount of regular flour. I prefer to mill a small amount from scratch because it is SO easy to do so with Thermomix and it enhances the flavour and aroma of this crust SO much! (My preference is a blend of freshly milled flour combined with regular flour, but you can do as you wish. )
note about caraway seeds: If you are fond of caraway seeds, add a heavy sprinkle. If you don't like caraway seeds, simply omit.
