just saying recipes aren’t part of the scientific method.
What year would you say the scientific method was devised?

You’re the expert, Eve, and I’m sure you’re ready to school me — which it’s worth noting is one common attribute of a lay positivist identified in that essay What Science Is Not I pointed you to. Anyway, I can Google with the best of them, and the earliest date I can come up with is 965–1039 AD, Ibn al-Haytham “a polymath considered by some to be the father of modern scientific methodology, due to his emphasis on experimental data and reproducibility of it’s results” (Wikipedia). I could be wrong, but I suspect cooking started before that.
