One of the things I love about modernist cooking and ChefSteps is that ingredients are given so precisely. Like in grams instead of cups. Also, many recipes give exact heat specification. But I noticed for stovetop cooking, direction is still given as medium heat, medium-high, etc.
I know that ovens differ. My last two ovens have been too low and I put a thermometer in and to get the recommended heat I need to go like 25F over. And I noticed improvements for obvious reasons.
TL;DR
So, my question is: should I expect the same thing on my stove? How can I calibrate this or test it? What temperature is supposed to correspond to each heat level? I never seem to hit it right. Or am I just missing something?
