A friend asked me to try to make a frozen treat with Yakult. Quick search online shows others have used this ingredient wit a custard or cream base, and traditional ice cream makers but no ninja. I thought I'd try it straight up 😁 The ingredients did me a concern, since it's water, couple types of sugar, skim milk, cultures, and some flavor - i.e. this is going to be very close to ice, and I think the instructions state not to blend pure water. 😇 But.. I had to try, so in went several of those plastic bottles to fill up the container and froze it for 24 hours.
The first spin made so much noise, so so much. Four spins later, it was still somewhat powdery, but a spoon mixed it up well. It had a citrus-like flavor, gave me a searing brain freeze almost instantly, and a very thin mouthfeel (actually, it was very close to snow, though I haven't seen or tasted snow in over 10 years).
Not recommended.
I am not sure if it makes sense to pursue this further.. I can add some inulin, fat, emulsifiers, gums, different sugars, maybe follow the Underbelly strawberry sorbet example, or I can do a little custard or mix with some heavy cream, but I think the latter will take away from the yakult flavor. Worth a pursuit? Thoughts?
My next idea is to freeze some greek yogurt. Or, maybe mix some jam into greek yogurt (or euro-style yogurt) and see what happens. I'm enthusiastic about testing things, though generally slow, so if someone beats me to it, please share results
