I have been giving this a lot of thought lately. Yesterday I made a Derby cheese and noticed that the two cheese books I use had very different times listed for the hard press press prior to removing from the mold. It reinforces this observation...
Some books are very precise in their recipes and give specific amounts/weights/times. Others are a bit looser (e.g., "firm pressure," that sort of thing).
My grandmother was an immigrant from an Eastern European peasant family. She was a fabulous cook, but never did it from a recipe. Everything was by feel, based on hands-on teaching from her mother and her own experience. And though I love recipes and cookbooks, I sometimes think that we get too caught up in exactness. Surely early cheesemakers and many peasant people never used written formulas!
So my question/thought: when/how do other people go 'off recipe'? Do you think that the commonly available books are useful, or constraining? Although I am a relative newbie, I find that I am already starting to rely on anecdotal information from others on this forum in place of prescribed practices. And thus far, I find that my results are largely pretty successful.
An example: I find that I have to remind myself that pressing something for an extra hour or two overnight is unlikely to ruin a particular cheese. And since I cook my milk in two unequally sized pots, I 'eyeball' the relative proportions of the added starters, rennet, additives, as splitting the recommended amounts results in 1/16 tsp. and similar measures in some cases.
I have been mainly trying semi-firm or hard cheeses, washed curd cheeses, and a few miscellaneous ones like cottage, mozzarella, and ricottas. Perhaps some of the finer/more complex cheeses are different?
I am curious as to what some of you more experienced cheesemakers think on this subject.
