Instructions: Peel onion and cut into 8 wedges.

Pour 1 teaspoon oil into a 2- to 3-quart pan over medium-high heat. When pan is hot, add onion and cook, turning once, to lightly brown, about 5 minutes.

Add orange juice and vinegar. Bring to a boil over high heat, then reduce heat, cover, and simmer until onion is very tender when pierced, about 45 minutes.

Shortly before onion is done, pour remaining oil into a nonstick 10- to 12-inch frying pan over medium-high heat. When pan is hot, add salmon. Cook, turning once, until fish is opaque but still moist-looking in thickest part (cut to test), 7 to 9 minutes total.

Transfer the salmon to plates and serve with onion mixture. Season with salt and pepper to taste.

This recipe yields 2 servings.

Comments: In Modena, Italy, the home of balsamic vinegar, Robin Love bought a small, expensive bottle of a complexly aged balsamic. At home, it disappeared quickly into dishes that it suited well. Hooked on this special sweet flavor, Love hit upon a less costly alternative - everyday balsamic vinegar plus orange juice. It goes nicely with salmon and onion, especially when served with a risotto made with asparagus and no cheese.
