It was an experiment deep down I knew shouldn’t have attempted but curiousity got the best of me. For if Hot Chocolate tasted best when milk was thev substrate (not sure what it means but sounds scientific) then why shouldn’t be the same with coffee. So I decided my Keurig needed to be the test tube as I poured Milk where the water usually is put. To make matters more complicated it wasn’t just milk but a fusion of milk and bananas. Needless to say the conclusion I drew from the experiment is sometimess curiousity can kill your Keurig machine or at least bring it to life support.
