This week mine was homemade soda. Fermented sodas, citric acid + bicarbonate sodas, different juices and flavors like lime + lemon + cherry and pomegranate or mango peach or cola (homemade knock off)
Thanks for the rec! Not sure why someone downvoted you, but I was able to find his playlist with music theory concepts after some digging. I'll use this to supplement the rest of the material I've found.
