Big Lou Holdings, the RFT’s St. Louis-based owner, announced today that it has purchased Sauce Magazine — and it plans to bring the venerable food-focused monthly back into print starting in December. Chris Keating, founder and CEO of Big Lou Holdings, said that beyond bringing back the print issue, he envisions few major changes to the 24-year-old magazine. “We wanted to buy Sauce because — like everyone in St. Louis who loves food — we love Sauce,” Keating said in a prepared statement.
