**Cookie Butter (Flavor Jungle) 1.5%/4% (6-3-24)** -- I'd heard this one was strong, so I tested it at both 1.5% and all the way up to 4%. My two main take aways were Speculoos Cookie, and Clove. In short it was like a spiced speculoos cookie with some lighter, creamier elements, but nothing stood out as an overt butter. Creamy-ish, yes, buttery, not really. The spice was fairly present, and while I didn't pick up on any ginger, this would work great in any mix with gingerbread in it. When comparing the lower and higher mix levels, I got a little dry-ness at the lower (1.5%), that I didn't get at the higher (4%). I was surprised it didn't get stupid at the higher rate. Not muted, but it wasn't a linear increase in strengh, maybe topped out at 2%. I didn't 100% fall in love with it, as it wasn't a pure Speculoos Cookie, and not truly Buttery'. Very tasty, with solidly present spice levels, that left the solid perch of JUST a Spec Cookie, and added in some creamy smoothness. Sweetness was below mid-level, and no off-notes, BUT, use with caution or the spice could run over your mix. Tasty, accurate, and no complaints other than wondering if a straight Spec Cookie might win out over this one. Leaving it still high at a **8.0/10**."
