Description Renée's Gourmet Foods is a saucy dish. The company makes refrigerated salad dressings, sauces, dips, marinades, and mayonnaise; all are made without using preservatives or additives. The company also produces and markets A.1. Steak Sauce in Canada. Its customers include foodservice operators. In business since 1985, Renée's Gourmet Foods was owned by founders Arnold and Renée Unger who put it on the auction block in 2006. After attracting attention from a handful of multinational food giants, the couple sold the company to Heinz Canada that same year.
