Is there a generally accepted notion of high/medium/low flame that can be expressed visually?
I ask before concocting my own guidelines for peewee chefs, 8yrs+. Because there is wide variation in stove tops (Esp internationally), I want clear direction easy to remember.
For example, maybe high flame licks the grate, while low only curls around burner head. Or maybe something about the color of the flame?
Anything that can help define medium is most useful since the knob establishes highest and lowest flame.
