Managing recipes is (or was, once upon a time) the definitive example of a use of computers which macho hacker types looked down their noses at.
But to me it seems like something quite useful. I’d like to collect the recipes I know and attach notes on the times I’ve made them, for instance; plus a list of things I’d like to try making.
If my handwriting wasn’t so bad, I’d do it on paper. JB· has a very nice binder of recipes which he outlined by hand, but still hasn’t put any actual recipes in as far as I can tell.
