- Makes 16 patties
- Whisk together all the sauce ingredients in a small bowl. Taste and adjust the seasoning. Set aside.
- To make the patties, heat 1 tablespoon of the oil in a large skillet over medium-high heat. Add the yam, onion, celery, and garlic. Cook, stirring occasionally, until tender, about 5 minutes. Remove from the heat and stir in the remaining ingredients.
- For each patty, gently squeeze about 1 tablespoon of the mixture in your hand to form a ball, then flatten into a 2-inch round patty. Place the patties on a plate as they are prepared.
- Wash and dry the skillet. Heat the remaining 1 tablespoon oil over medium-high heat. Cook the patties for about 3 minutes on each side, or until lightly brown. Transfer to a plate. Serve the sauce in a small bowl for drizzling it over the warm patties.
