Tried lots of those things. Fun stuff. Work. I’m glad I know how to do it though. Growing Kefir was one of my favorite things though. I loved watching the stuff turn into tart goodness.
Mason jars are my favorite drinking utensil for cold drinks. I grew up with mason jars. My Mom was too busy to be a hippie, and yet she raised us with Yogurt, homemade sourdough bread, big garden, composting and all that stuff, all Mother Earth News before it went-glossy,etc. so it’s part of my “normal”.
