Preheat the oven to 400 degrees. Prepare a sheet pan with parchment paper and set aside.
In a large bowl add cumin, smoked paprika, turmeric, garlic powder, crushed red pepper, salt, cinnamon and oil. Mix until the spices are fully incorporated in the oil.
Add the cauliflower florets and toss to coat the cauliflower in the oil and spice mixture.
Place the cauliflower florets on the prepared sheet pan in one layer.
Roast for about 25-30 minutes or until the cauliflower is tender and golden brown.
While the cauliflower is roasting, mix together the ingredients for the sauce in a small bowl or blender.
Serve the cauliflower with the dipping sauce.
