Excellent project. Very well written and executed. Love it.
I've found that I can get excellent consistency in coverage by slicing the banana vertically to get long rectangular slices and then laying the slices side-by-side - generally about 4-5 across.
Over many years, I have highly optimized my PB&B production process:
1. Apply peanut butter to bread. (Copious amounts. I prefer Adam's.)
1. Peel banana and cut length-wise. Place one half across top of bread where the loaf curves. Use curve of banana to match curve of bread. Cut off part of banana that hangs off.
2. Invert other half of banana and place it parallel to first piece, slightly tucked under. Cut overhang.
3. Take the two overhanging pieces, and place them next to each other on the remaining third of the bread.
With a properly sized banana and loaf, this provides almost perfect uniform banana coverage, requires only three cuts, and dirties only one knife.
If you were a machine learning model (or my wife), then you would tell me to just cut long rectangular strips along the long axis of the banana, but I’m not a sociopath.
