Yep. HP sauce did this. Used to be ubiquitous on restaurant tables in Canada. Then they changed the recipe, white vinegar instead of malt, no rue flour, orange juice concentrate instead of tanarind puree, new version was sharper, more astringent, less sweet n smoky. Everyone just quit buying it without even really noticing why. Then the old recipe started showing up in "ethnic food" aisles in areas with high dutch and English immigration.
