tl;dr: (read the whole article for more than you ever wanted to know about banana ripening. Serious Eats does deep food dives. One of the few food blogs I follow.)

slow ripening by wrapping stems in in plastic, cooler temperature (not fridge!), and separate them.

speed up ripening, warmer temperature, bagging doesn’t do much.

See taped stems on the right; author used scotch tape, but I’m thinking plastic wrap would work. needs testing.
