Mmmmmm.....mandarin! Not quite as good as the lemon, but still pretty good. Been making a litre just about every day since October last year and have managed to keep the original culture alive.
I've reduced the powdered milk to 20 grams per litre and it's still getting plenty of body. The main influence on this seems to be maintaining the milk at 80 deg C for about 30 minutes before cooling and adding the culture, (the Instant Pot makes that a snack to do). In the end, I stuck with the St and Lb culture mix as the aBc culture was becoming stretchy, (like the EasiYo banana flavour used to).
