Red Snapper with Green Peppercorn Sauce

Foil-wrapped fish, what French cooks call en papillote, is the trick to keeping delicate red snapper tender and moist. Sealed in buttered foil and baked twelve minutes, the fillets steam in their own juices and emerge flaky without ever drying out.

The green peppercorn sauce does the heavy work of making this a date-night dish. Bottled clam juice and dry white wine reduce hard to concentrate the seafood and acid notes, then heavy cream goes in and reduces again to a velvety body. The whole sauce takes fifteen minutes start to finish.

Green peppercorns are the unripe seeds of the same plant that gives us black peppercorns, but they have a gentler heat with a clean herbaceous note. Look for them brined in jars at well stocked grocers. Adding them at the last second preserves their pop and prevents the heat from going bitter.

A splash of caper brine or vinegar at the end balances the rich cream sauce with acid. Skip this and the sauce flattens out on the palate.

Pro Tips

• Crimp the foil packet seams tight, any steam leak and the fish dries out
• Pat the fillets dry before placing on the foil for a cleaner flake without watery juices
• Reduce the wine and clam juice fully before adding cream, the alcohol needs to cook off
• Drain green peppercorns well before adding, the brine is too salty for the finished sauce
• Open the foil packets carefully, the trapped steam burns hot

Variations

• Swap snapper for halibut, sea bass, or another firm white fish based on what is fresh
• Add a tablespoon of cognac to the wine reduction for a classic French steakhouse finish
• Stir in a teaspoon of Dijon mustard with the cream for a sharper sauce profile

Serve with steamed rice, buttered potatoes, or crusty bread to mop the sauce.
