Raspberry Mirepoix

A refined sauce that takes the classic mirepoix base of celery, carrots, and onions and brightens it with orange juice, fresh ginger, and raspberry vinegar. This is a light, glossy pan sauce designed to complement fish, chicken, or shellfish without overwhelming them.

The vegetables simmer in a light chicken bouillon until crisp-tender, so they keep their color and a bit of bite. Then a cornstarch slurry mixed with orange juice, ginger, and raspberry vinegar goes in to thicken the sauce into a silky glaze. The whole thing comes together quickly and tastes much more sophisticated than the short ingredient list suggests.

Raspberry vinegar is the star. It adds a tart, fruity acidity that balances the sweetness of the carrots and orange juice. If you’ve never cooked with it, this is the recipe to start.

Kitchen Tips

• Dice the vegetables small and uniform. They’re part of the sauce, not a side dish, so you want them fine enough to sit on top of a piece of fish.
• Stir constantly once you add the cornstarch mixture. It thickens fast and can clump or scorch if you’re not paying attention.
• Keep the vegetables crisp-tender. Mushy carrots and celery lose their color and turn the sauce muddy.
• This sauce is best served fresh. It doesn’t reheat well since the cornstarch breaks down and the glaze turns thin.

Variations

• Swap raspberry vinegar for balsamic vinegar and omit the orange juice for a richer, more savory version.
• Add a pinch of red pepper flakes for subtle heat alongside the fruity tang.
• Use shallots instead of green onions for a more delicate, sweeter base.
