So the reason that they're telling you to use the, um, those other milks besides soy milk is primarily because of the fat content. Um, you know, the fat content, uh, the keefer actually helps to react with those and that's kinda what makes that coagulated um, you know, yogurt that the keefer kind of helps to be able to do. So typically people would use a coconut milk or an almond milk, um, but the package and the instruction of the keefer say to specifically use coconut milk, it might be engineered specifically to react with coconut milk to be able to make a keefer. You can definitely try the soy, but you might not get the same reaction as you want to. Um, and that kind of fermented, you know, kind of um, like thicker version of that as well too. Um, so, uh, you might want to give it a try to be able to see if it works, but if the package is saying to be able to use it on those, um, on specifically coconut milk, that might be something you wanna be able to do on that or you might want to follow the directions for. Um, otherwise, you know, um, oh that's interesting that it says coconut water 'cause there's not a whole lot of fat content on that either. Um, but if it's saying to use it on the just juice or coconut water, it doesn't seem like it worries about the fat content. So give it a try. The worst thing you have, you know, if you're just losing a little bit of that starter powder, that's, that's okay. Um, you know, and I wouldn't use the entire kit for it just to be able to do a sample. A lot of times when I'm using a new uh, probiotic, um, I'll often test them, you know, overnight to be able to make sure that they're still living and active. So I'll add, uh, a little bit of a probiotic basically to a non-dairy milk, um, and set it into the fridge and be able to see if I have kind of a yogurt like texture the next day just to make sure that it's active. So that's probably what I would suggest to do with this is just take about three tablespoons of the soy milk and put a little bit of the key for powder into it to be able to see what happens overnight when it let, when you let it sit.
