I have to have it written or printed out if it's from/on my computer. If printed, I put it in a clear plastic 3 ring binder sheet. If not I probably would never be able to read it thru the butter I drop on it. Pencil scribble on an envelope, if successful then I put it on the computer with my notes. If printed I add the word Printed on the computer at the top so I don't accidently print it again.
Notes are added at the bottom and with an asterisk beside the ingredient, if the change is there - of course if there is room I add it beside the ingredient. ex.
no salt! or
subbed sour cream.
If it's good - I write at the top
YUM! - DELISH - 5 Star! or something like that.
I also add the date at the bottom/on the back. If I had it or made it with someone. Plus I add subsequent dates if/when I make it again, especially if I make a booboo or change something, like putting it in the oven and then seeing the garlic had been pushed under the foil or looking at the recipe and realizing I never did go get the celery from the other fridge for the mise en place. Or even
"OOPS - Don't do that again!"
I know it's more work, but I try to make sure the notes are written on the paper and is transcribed onto the 'puter one as well.
If I saved the recipe on the 'puter from the net and printed it out from there, if it's good, I transcribe it into a Word doc. All that just so I can access it without the internet.
