Also known as chufa or earth almonds, tiger nuts are small tubers that are touted for nutritional benefits, with prebiotic fiber, iron, potassium and other vitamins and minerals. “Nuts” is a misnomer — the crop is actually nut-free, as well as gluten-free, dairy-free and vegan friendly.

“Tiger nuts have a tie-in with the Paleo diet; it’s a loophole,” Ms. Mattucci said.

A Brooklyn-based company called Organic Gemini offers several products featuring the ingredient, including TigerNut Flour, a baking alternative for gluten-free, nut-free products; and TigerNut horchata beverages made with pureed vegetables. The company also sells tiger nut granola, tiger nut oil, and raw tiger nuts in bulk.
