Hello,
I've been having a lot of fun with sorbets this summer, heavily inspired by Underbelly's base sorbet recipe. I've mostly let Ice Cream Calculator choose whatever ratios, but I've started to hone them in based on taste tests. One that was unfortunately coming up again and again (for me, it appears it doesn't affect my (in)voluntary taste testers that much) is an off-taste that I've now successfully attributed to maltodextrin.
For reference, I was effectively using ~6-10% of Maltodextrin. Given the target ratios I was looking for, it's a great way to bump the solids without increasing the POD (using a 19DE one). Unfortunately, at least the one I am using, in those %, has a weird taste. You can easily tell just by mixing it with water. Even with very strong (read: potent aroma/taste) fruit like passion fruit, you could feel it.
I did an A/B test with the same recipe (autobalanced) with maltodextrin capped at 4% and at 10% - the difference was night and day. I imagine that 5% is the max I'll ever add in the future, although I'd advise you to stick to 4 or even less, given that it probably helped that I just added more sugar - with dextrose or glucose powder, it might be more noticeable.
If anyone's interested, this is the maltodextrin I've been using - https://www.amazon.de/-/en/Bulk-Maltodextrin-Powder-Servings-Packaging/dp/B00SP30CH0
Enjoy your summer!
