That might be true in some cases but I don’t think it’s generally true. The black specks are the seeds inside the vanilla bean; they’re where the most flavor is concentrated.
Some of them are white so you’ll think it’s vanilla.
I bet if you were blindfolded and tasted a spoonful of store-bought chocolate pudding and one of vanilla, you wouldn’t know which was which.
Hey thanks! Coincidentally, I pretty much only use the stuff to create stubborn stains on the floor.
And after extraction, this waste product is sold to entice gullible consumers.
