Making soap basically requires two ingredients: fat and lye. Micha Magid, an owner of Mighty Quinn’s Barbeque, with a number of stores in New York and New Jersey, had a lot of fat in his kitchen. “We would trim the whole briskets before smoking them and were throwing away tons and tons of fat,” he said. “I was looking for a way to repurpose it.” He started making soap with the fat, plus lye, peppermint oil and organic charcoal. “It seemed to be a really good idea now that everyone has to wash their hands all the time,” he said. The blocks of charcoal gray soap are effective, and are sold in its stores and on the company’s website. Mighty Quinn’s is donating 25 percent of sales to No Kid Hungry.
