I would like to demonstrate two types of simple keep-on-the-counter-like-a-pet dairy ferments.
Milk kefir: I keep a jar of milk kefir on my counter and feed it every day. I scoop up the blob of grains into a new jar and fill the new jar with milk. Cover with a paper towel or a coffee filter and keep on with a jar lid ring or rubber band. I got the grains from this place and here are their instructions (
NWFerments). You have to feed the grains a few times before they are properly re-hydrated and after that they will start to grow with each feeding. Most people say to strain the finished kefir but I can find the grains just fine and the kefir is just going into the blender so I find that step unnecessary.
Viili yogurt: I just got this new culture to try and was amazed that it really did turn into yogurt even though I am used to doing the whole process for greek yogurt where you heat it up and then keep it at a certain temperature all day. I just put the packet of cultures into some milk and left it until the next day. The flavor/smell reminds me of kefir but it is definitely distinct. I got the culture from the same place as the kefir (
NWFerments).
Another dairy ferment with the same process is sour cream. I've been making kefir sour cream so that probably counts as a duplicate so I won't put pictures here, but I wanted to mention it.
