Dipping Sauce: Add all ingredients to a bowl and stir until smooth. Add a little milk to reach a sauce consistency. Refrigerate until ready to use.

Sweet Potatoes: Slice potatoes, skin on, into 1/4 thick long slabs or rounds. Add to a baking tray or bowl. Drizzle olive oil and honey on top. Sprinkle with garlic, turmeric, salt, and pepper. Toss to coat.

Cook on a medium-high grill for a few minutes on each side until charred and tender.

Serve with sauce on the side for dipping or sauce drizzled on top.
