Mustard-Pepper Sauce

This sauce takes the peppery bite of mustard greens and builds on it with fresh green chiles, ripe tomato, cilantro, and a whisper of Dijon for double the mustard punch. Cumin and coriander add a warm, earthy backbone that reads distinctly Indian, while a finish of heavy cream rounds the heat into something silky and spoonable.

Pureeing the greens, pepper, tomato, and aromatics first means you skip a long simmer; five minutes in hot oil wakes up the spices and takes the raw edge off the garlic and chiles. Once the cream goes in, a covered simmer of 12 to 15 minutes is all it takes to thicken into a pourable sauce. The result clings to seared fish fillets, coats shrimp, or soaks into cubes of firm tofu beautifully.

Kitchen Tips

• Use Swiss chard if you cannot find mustard greens; the color holds but the heat drops a notch, so bump up the Dijon.
• Seed the green chiles for a milder version, or leave them in for full kick.
• Toast the cumin and coriander in the pan for 30 seconds before adding the puree to deepen the flavor.
• Taste before serving; the tomato can lean tart and may want a pinch more sugar.

Variations

• Swap cream for full-fat coconut milk to make it dairy-free.
• Stir in a teaspoon of grated fresh ginger with the puree for extra warmth.
• Finish with a squeeze of lime juice off the heat for a brighter, sharper profile.
