Admittedly, Raspberry Butter Sauce walks a fine line between a sauce and a salad dressing. Drizzled over crispy, pan-seared salmon on a bed of greens, it is both of these things at once. The flavor is fruity and slightly sweet, balanced by a tangy zip of acidity from red wine vinegar  and a pinch of sea salt . Add a few fresh raspberries  to the salad and you have a perfect summer meal.
Compared with other types of fruit , raspberries are lower in sugar and they’re also loaded with fiber, vitamin C, manganese and antioxidants. Raspberries add a burst of sweet acidity to salads and are especially good with salmon and pork. In fact, this salad topped with Raspberry Butter Sauce would be equally delicious with slices of crispy grilled pork.
Straining the sauce through a fine mesh sieve is optional, but recommended if you want a silkier, lighter texture and a flavor that’s more tangy than sweet. You’ll only end up with a tablespoon or two of sauce/dressing, which is fine, because a little bit of the flavor goes a long way. This isn’t a sauce to drown a meal in. It’s one to drizzle lightly to bring a little taste of summer to your plate.
- 2 salmon filets, skin  on
- 1 tablespoon oil (for searing salmon)
- 20 fresh raspberries (or fewer, for a flavor that is less sweet)
- 2 tablespoons unsalted butter, melted
- 1 1/2 teaspoons red wine vinegar
- Pinch of sea salt (about 1/8 teaspoon)
Lightly salt both sides of the salmon.
Heat oil in a frying pan/cast iron skillet over medium-high heat until the oil is good and hot and starts to crackle a little. Place the salmon in the pan, skin side down, and cook until it is nicely browned and more importantly, no longer sticks to the pan, about 3 minutes. If you turn the fish too soon, it will stick and the skin will rip off, so be patient.
Flip the fish over and cook on the other side, about 3-5 minutes more for a filet that is 1 – 1 1/2 inches thick. If the middle is still not cooked enough for you after this amount of time, lower the heat a little and cover the salmon with a lid for a few minutes more.
To make the Raspberry Butter Sauce, blend the raspberries and melted butter in a blender until smooth.
Scrape into a bowl and mix in vinegar and sea salt. Optional: Strain the sauce through a fine mesh sieve set over a bowl, pressing down on the solids to push out the liquid. You’ll only end up with about 2 tablespoons of sauce/dressing.
Toss with greens and/or drizzle over the salmon.
