Very nice :) As a fellow bread baker/chemist/geek, I wrote this little command-line tool in Haskell that helps me scale recipes. I've used it to develop/store/print out recipes and routinely for dinner breads like tortillas and rotis ("OK so I just dumped 113 g of durum atta into a bowl; how much water, oil, and salt do I need?")
