Over in the refrigerated section, Tony Roma's Pulled Pork in BBQ Sauce (which says it's Premium Restaurant Quality) contains no corn syrup at all: it's made with real sugar. (And it tastes fantastic!)
Why the difference? The bottled sauce is manufactured by Greystar Products, while the 18 oz. tub comes from Rupari Food Services — a company whose primary business is supplying restaurants.
What do you get if you order BBQ sauce online? Hopefully, the real deal.
(Looking for a decent BBQ sauce on store shelves? Try Bulls-Eye, although their current "original" isn't the same as it was a year or two ago: they've upped the sodium content.)
