Step 1

Bring the water to a boil in a medium saucepan. Add the cauliflower, onion powder, garlic, paprika, mustard, and turmeric. Cover tightly and reduce the heat to very low. Simmer until the cauliflower is so tender that it easily comes apart when poked with a fork, about 15-20 minutes.

Step 2

Carefully transfer the contents of the saucepan to a blender. Add all remaining ingredients. Cover and blend, starting on low and increasing the speed until you’re at the highest setting. (Be careful–hot foods can “erupt.”) Blend until you have a completely smooth sauce.

Step 3

Pour the sauce back into the saucepan, add salt to taste if you like, and heat until it begins to bubble, stirring occasionally. Allow it to cook and thicken for at least another 2 minutes. Serve hot.
