From Fine Cooking Magazine - "This sweet-tart glaze along with the heat of crushed red pepper and sweet smoked paprika, and the depth of coriander -- give a mellow cauliflower a zesty profile".
Heat 3 tablespoons oil in a heavy duty 12-inch skillet (preferably cast iron) over medium-high heat. Add the cauliflower and 1/2 teaspoons salt and stir to coat. Cook, without stirring, until the cauliflower is browned on one side; about 4 minutes. Turn each piece over and cook, without stirring, until evenly browned on the second side, about 4 minutes more. Reduce the heat to medium and continue cooking, stirring often, until browned all over, about 4 minutes longer.
Meanwhile, in a small bowl, stir 2 tablespoons water and the remaining 1 tablespoons oil with the onion, honey, ground coriander, paprika and pepper flakes.
Add the onion mixture to the skillet and cook , stirring occasionally, until the onion is softened, about 1 minute. Continue cooking, stirring constantly, until most of the liquid has evaporated and the cauliflower is glazed, about 4 minutes. Transfer to a serving bowl, stir in the lemon juice and zest, and garnish with the cilantro. Serve immediately.
