I asked on IG why my Costco bananas won’t ripen and I received thousands of mesaages. No, they are not plantain, definitely bananas. They were also not sold as green bananas for cooking. Did you know bananas are sprayed with ethylene to speed up the ripening peocess. Mine were probably not sprayed or somehow missed. Putting the bananas in a brown bag traps the natural ethlyene that it produces which helps speed up the ripening peocess. #themoreyouknow #fruittok #lifehack #kitchenhacks
