“How did you get your popcorn to be so small?” Ari Taube hears that a lot. He’s delighted to explain that Mini Pops, the certified organic snack food he makes in Stoughton, isn’t corn at all. It’s air-popped sorghum, but it looks like miniature popcorn. In 2009, Taube caught a TV segment showing popped sorghum in Ethiopia; intrigued, he made a batch, and soon decided to sell the stuff. He spends a lot of time talking about the difference between corn and sorghum, and says, “Once people know, their reaction is, ‘This is really cool.’ ” Mini Pops are available at Natural Food Exchange, 343 Main St., Reading, 781-944-8498; Good Health Natural Foods, 1627 Hancock St., Quincy, 617-773- 4925, and 219 Columbia Road, Hanover, 781-826-0808; Roche Bros.
