Sous Vide Salmon
Gentle cooking keeps the salmon moist and evenly pink. A brief skin-side sear adds texture without cooking the center much further.
Ingredients
- 4 pieces skin-on salmon, 5–6 ounces each and about 1 inch thick, pin bones removed
- 1 teaspoon kosher salt, or to taste
- 1 tablespoon ghee
Instructions
- Heat a sous vide bath to 125°F / 52°C. Season the salmon evenly with salt and seal in a single layer in suitable cooking bags, using gentle vacuum pressure or water displacement.
- Cook for 45 minutes for pieces about 1 inch thick. The salmon should be softly set and moist; thicker pieces require additional time.
- Remove from the bags and gently blot dry, paying particular attention to the skin.
- Heat the ghee in a nonstick or well-seasoned skillet over medium-high heat. Add the salmon skin-side down and press very gently for the first few seconds to maintain contact. Sear for 60–90 seconds, until the skin is lightly crisp. Do not flip; transfer directly to warm plates.
Notes
- This low-temperature preparation is not pasteurized. For higher-risk diners, cook salmon to an internal temperature of 145°F / 63°C instead.
- Keep the sear brief: the fish is already cooked and delicate.
Sweet Corn Purée
Blended fresh corn makes a sweet, golden sauce without needing cream. Butter rounds out the texture while a little lemon keeps it from tasting heavy.
Ingredients
- 4 ears sweet corn, kernels cut off and cobs scraped for their milk
- 2 tablespoons unsalted butter, divided
- 1 small shallot, thinly sliced
- 1/2 cup water, plus more as needed
- 1 teaspoon fresh lemon juice, plus more to taste
- 1/2 teaspoon kosher salt, or to taste
Instructions
- Melt 1 tablespoon butter in a saucepan over medium-low heat. Add the shallot and cook for 3 minutes, until translucent without browning.
- Add the corn kernels, scraped corn milk, water and salt. Cover and simmer gently for 7–9 minutes, until the kernels are tender.
- Transfer to a blender and blend until very smooth, venting the lid safely for hot ingredients. Blend in the remaining butter and lemon juice.
- For a particularly silky sauce, pass through a fine-mesh sieve. Adjust with warm water until it spreads easily across a plate but still supports the salmon. Taste for salt and lemon.
- Keep warm over very low heat, stirring occasionally and avoiding a hard boil.
Notes
- Corn sweetness and starchiness vary; add water a tablespoon at a time rather than aiming for a stiff mash.
Sungold Tomatoes and Basil
Fresh tomatoes and torn basil brighten the warm corn and salmon, adding acidity and a loose, summery finish.
Ingredients
- 1 pint Sungold cherry tomatoes, halved
- 1/2 cup loosely packed basil leaves
- 2 teaspoons extra-virgin olive oil
- 1 teaspoon fresh lemon juice
- 1 pinch flaky sea salt
Instructions
- Just before serving, gently toss the tomatoes with olive oil, lemon juice and salt.
- Tear the basil into large pieces and scatter over the plated salmon and corn, along with the tomatoes and their juices.
Roasted Whole Okra
Roasting dry, whole pods keeps them intact and limits slippery cut surfaces. High heat brings out their grassy sweetness and lightly blisters the skins.
Ingredients
- 1 lb small, tender okra pods
- 1 1/2 tablespoons olive oil
- 1/2 teaspoon kosher salt
- 1 teaspoon fresh lemon juice
- 1 pinch flaky sea salt, for finishing
Instructions
- Heat the oven to 425°F / 220°C. Wash the okra and dry thoroughly. Trim only the tough stem tips, leaving the pods closed.
- Toss with olive oil and kosher salt. Spread on a sheet pan in a single layer with space between the pods.
- Roast for 18–22 minutes, turning once, until tender and lightly blistered but still holding their shape.
- Finish with lemon juice and a small pinch of flaky salt just before serving.
Notes
- Choose small pods; large, woody okra will not become tender with roasting.
Deeply Roasted Sunchokes
Small skin-on pieces develop dark, caramelized edges while the interiors become creamy. Their earthy flavor balances the sweetness of corn and tomatoes.
Ingredients
- 1 lb sunchokes, scrubbed well
- 2 tablespoons olive oil
- 1/2 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
- 1 teaspoon fresh lemon juice
- 1 pinch flaky sea salt, for finishing
Instructions
- Heat the oven to 425°F / 220°C. Dry the scrubbed sunchokes and cut into roughly 3/4-inch pieces, leaving the skins on.
- Toss with olive oil, kosher salt and pepper. Spread on a sheet pan, placing flat cut sides against the pan where possible.
- Roast for 35–45 minutes, turning after about 25 minutes, until deeply browned at the edges and completely tender when pierced.
- Toss with lemon juice and finish with flaky salt. Serve promptly to preserve the crisp edges.
Notes
- Sunchokes are rich in inulin and can cause digestive discomfort; the portion here is intentionally modest.
Overall Timing / Workflow
The salmon and sunchokes cook largely unattended, leaving time to blend the corn and finish the vegetables. Searing the fish last protects its delicate texture.
Instructions
- 0:00 — Heat the oven to 425°F / 220°C and the sous vide bath to 125°F / 52°C. Scrub and cut the sunchokes, then prepare the salmon.
- 0:10 — Put the sunchokes in the oven and the salmon in the water bath.
- 0:15 — Cut the corn from the cobs and make the purée. Keep it warm over very low heat.
- 0:30 — Put the okra in the oven on a separate sheet pan. Turn the sunchokes as needed for even browning.
- 0:45 — Halve the tomatoes, prepare the basil and warm the serving plates. Check both vegetables for tenderness.
- 0:55 — Remove the salmon from its bags, dry thoroughly and sear skin-side down. Loosen the corn purée if needed, dress the tomatoes and plate immediately.
Notes
- Allow about 60 minutes total, with the sous vide bath and oven heating while you prepare the ingredients.
Plating
A shallow pool of corn ties the salmon and tomatoes together, while keeping the roasted vegetables mostly outside the sauce preserves their texture.
Instructions
- Spoon a broad, shallow pool of warm corn purée across one half of each warm plate.
- Set a salmon portion skin-side up on the purée. Scatter Sungolds and large torn basil leaves around and partly over the fish.
- Arrange the roasted sunchokes and whole okra in separate groups beside the salmon, keeping most of their browned surfaces clear of the purée.
- Spoon any tomato dressing around the corn and serve immediately.
Leftover Path
Separate storage protects the vegetables from the sauce and makes it possible to reheat each component appropriately.
Instructions
- Refrigerate leftovers promptly, within 2 hours, in separate shallow containers. Eat the low-temperature salmon within 1 day; keep the corn and roasted vegetables for up to 3 days.
- Reheat the corn gently in a saucepan with a splash of water. Re-crisp the sunchokes and okra in a 425°F / 220°C oven for 8–12 minutes.
- For a hot leftover meal, reheat the salmon to 165°F / 74°C; it will be firmer than when first served. Alternatively, use promptly chilled salmon cold the next day with the remaining tomatoes and fresh basil.
