Ingredients

1/2 c. plus 2 tablespoons extra-virgin olive oil

1 tbsp. Dijon mustard

6 6-to-7-ounce center-cut salmon fillets with skin

3/4 c. Riesling

3 tbsp. mayonnaise

1/4 c. minced chives

1/4 c. chopped basil

3 tbsp. chopped cilantro leaves

1 small Scotch bonnet chile

Salt and freshly ground pepper

2 tbsp. (1 ounce) unsalted butter

1 large onion

12 3/4-inch slices of sourdough baguette

Preparation

Step 1In a large glass baking dish, blend 2 tablespoons of the olive oil with the mustard. Add the salmon fillets, turn to coat and refrigerate.Step 2Preheat the oven to 500°F. In a small saucepan, boil the Riesling over moderately high heat until reduced to 1/4 cup, about 7 minutes. Remove from the heat and let cool.Step 3In a medium bowl, whisk the mayonnaise with 6 tablespoons of the olive oil. Whisk in the wine reduction, chives, basil, cilantro and Scotch bonnet. Season with salt and pepper.Step 4Melt the butter in a medium skillet. Add the onion and cook over moderate heat until softened and starting to brown, about 8 minutes. Place the baguette toasts on a baking sheet and top with the onion. Bake in the upper third of the oven for 1 minute.Step 5Meanwhile, in each of two medium skillets, heat 1 tablespoon of olive oil until shimmering. Season the salmon with salt and pepper and add 3 fillets to each skillet, skin side down. Cook over high heat until the skin is browned and crisp, about 4 minutes. Turn the fillets and cook over moderately high heat until an even pink throughout, about 5 minutes.Step 6Spoon the chile-herb sauce onto plates. Top with the salmon fillets and serve with the onion toasts.Step 7Make Ahead: The salmon can marinate in the refrigerator overnight.Step 8Wine Recommendation: The elegant fruit in a Riesling can highlight the equally refined hint of fruit in the Scotch bonnet sauce here. But the sauce isn’t just fruity, it’s spicy. A bottling from the Rheingau area of Germany, like the 2003 Schloss Vollrads Kabinett, offers a bit of sweetness to cool the heat.

Riesling’s perfect match.
