Mark Bittman's recipe for Manchurian-Style Cauliflower calls for a sauce that is made from 1 cup ketchup (cooked until thickened) along with a little bit of garlic and cayenne. That's it. Now, I don't need the recipe to be authentic, and in fact the simplicity of this appeals to me, but I'm wondering if this sauce can actually taste good when it's mostly ketchup. Has anyone tried this recipe? How was it?
