Preheat oven to 425 F.
Chop cauliflower into florets.
Mix all batter ingredients together, adding the milk and water last.
Coat cauliflower in batter, place on a baking sheet, and bake for 22-25 minutes, flipping half way.
Make the sauce by combining everything in a small bowl. Thicken it for a couple minutes on the stove.
Use tongs to coat the baked cauliflower in the sauce. Bake for another 15-20 minutes, or even longer for more crispness.
For the chutney, just blend all the ingredients in a small processor.
