If your looking for a something different from a sweetener rather than sucralose or stevia then OoO sweetener is a nice change of pace, my favorite sweetener now. I initially heard from someone else about there sweetener, I am not crazy about sucralose and stevia is better but not great. He told me that OoO sweetener is not stevia or sucralose based, I confirmed this by calling OoO. They would not say what is in there sweetener, just confirmed it is not stevia or sucralose. When I got it I gave it a smell and it smells a little like a weak lemonade. I called OoO to ask if maybe they got my order wrong, they said no, there sweetener has a citric note to it.
I can only guess that they use citric acid in there sweetener but it is really good, not fake or have that after taste you get with sucralose and not overly sweet at times like Stevia.
I picked up some of there other flavors to give them a shot. I like the flan, sweet ice cream, french toast and sugar butter cookies. Not crazy about the custard and the other few flavors I got smell good but haven't tried them yet.
The Sweetener is a definite re-order for me, maybe the Sweet Ice Cream as well only because it is unlike any other flavor I have. The later is way more on the sweet than ice cream side and not a standalone but that extra something in a mix. If you like really sweet though the Sweet Ice Cream can be used alone or with fruits. If there pricing was better than I would probably re-order the flan and sugar butter cookie as well, at $3.49 and up for 10ml though you can get very similar flavors with CAP or TFA though at lower prices.
