Recipe 1 — Pan-Seared Wild Halibut

Ingredients

• 4 wild-caught Alaskan halibut fillets (about 6 oz each, skin off)

• 2 tbsp extra virgin olive oil

• 2 tbsp grass-fed butter

• 1 tsp Baja Gold sea salt

• ½ tsp freshly cracked black pepper

• Zest of 1 lemon

• 4 sprigs fresh thyme

Method

1. Take the chill off. Pull the halibut from the fridge 20 minutes before cooking.

2. Season. Pat the halibut completely dry, then season it with salt and pepper.

3. Sear. Heat the olive oil in a large cast iron skillet over medium-high heat until shimmering. Lay the halibut fillets in, presentation side down, and sear 3-4 minutes without moving them, until deeply golden.

4. Flip and butter-baste. Flip the halibut. Add the butter and thyme sprigs. Tilt the pan and spoon the melted butter over the fish again and again for 2-3 minutes, until it's just cooked through and opaque in the center, about 130-135°F. Halibut is lean and overcooks quickly, so pull it as soon as it's there.

5. Rest. Transfer to warm plates and let it rest 2-3 minutes. Finish with the lemon zest; added now, it stays bright instead of scorching in the pan.

Recipe 2 — Brown Butter Cauliflower Purée

Ingredients

• 1 large head cauliflower, cut into florets (about 6 cups)

• 2 garlic cloves, peeled

• 4 tbsp grass-fed butter

• 2-4 tbsp of the steaming water, as needed (or a splash of cream for extra richness)

• 1 tsp Baja Gold sea salt

• ¼ tsp freshly cracked white pepper (or black)

• Pinch of freshly grated nutmeg

• Optional: 2 tbsp grated Parmigiano-Reggiano DOP

Method

1. Steam the cauliflower. Steam the florets and garlic 10-12 minutes until very tender. Let them steam dry in a colander for 2 minutes so the purée doesn't turn watery.

2. Brown the butter. In a small skillet, melt the butter over medium heat. Cook 3-5 minutes, swirling often, until deeply golden-brown and nutty-smelling. Watch closely, because it can burn quickly.

3. Blend. In a high-speed blender or food processor, combine the cauliflower and garlic, brown butter (scrape in all the browned milk solids; that's where the flavor lives), salt, pepper, and nutmeg. Blend on high 60-90 seconds until silky smooth, adding the steaming water (or cream) a splash at a time until it's velvety and spoonable.

4. Taste. Adjust the seasoning, and fold in the optional Parmigiano.

Recipe 3 — Grilled Asparagus

Ingredients

• 1½ lb fresh asparagus, tough ends trimmed

• 2 tbsp extra virgin olive oil

• 1 tsp Baja Gold sea salt

• ½ tsp freshly cracked black pepper

• Juice of ½ lemon

• Flaky sea salt

Method

1. Toss the asparagus with the olive oil, salt, and pepper.

2. Grill over medium-high heat (or in a cast iron grill pan) 4-6 minutes, turning once, until charred and tender-crisp. Lay the spears across the grates so they don't fall through.

3. Finish. Squeeze the lemon juice over the top and scatter with flaky sea salt.

Recipe 4 — Lemon-Basil Oil

Ingredients

• 1 cup fresh basil leaves, packed

• ½ cup extra virgin olive oil

• Zest of 2 lemons

• 2 tbsp fresh lemon juice

• ½ tsp Baja Gold sea salt

• Optional: 1 small garlic clove

Method

1. Blanch the basil. Dip the basil in boiling water for 5-10 seconds, then transfer it to ice water. This keeps the green color vivid. Pat it dry.

2. Blend. In a blender, combine the basil, olive oil, lemon zest, lemon juice, salt, and optional garlic. Blend 30-45 seconds until bright green and smooth. It will separate a little as it sits; just stir before drizzling.

3. Strain (optional). For a silky, glossy finish, strain it through a fine-mesh strainer. Skip this for a more rustic texture.

Plating

Spoon the warm cauliflower purée in a wide swoosh across warm plates. Rest the halibut on top. Arrange the asparagus alongside. Drizzle the lemon-basil oil generously around the plate. Finish with flaky sea salt, a lemon wedge, and a fresh basil leaf.

Sourcing (essential picks)

• Wild-caught Alaskan halibut — hook-and-line-caught Pacific halibut from Alaska, from a trusted fishmonger or Vital Choice. Skip Atlantic halibut, which is depleted and on Seafood Watch's "avoid" list. Peak season March-November; frozen-at-sea is excellent year-round

• Fresh asparagus — bright green, firm stalks, from a farmers' market. Thicker spears are easiest to grill. Peak spring

• Cauliflower — organic, tight compact head

• Fresh basil — organic, bright green

• Grass-fed butter — cultured butter from 100% grass-fed cows, or raw butter from a local dairy

• Cream (optional) — raw cream from a small pasture-raised dairy, or Kalona SuperNatural (grass-fed, low-temp vat-pasteurized, non-homogenized)

• Parmigiano-Reggiano DOP (optional) — aged 24+ months, made from raw milk by law

• Fresh lemons — organic (you're using the zest)

• Fresh thyme and garlic — organic, hardneck garlic

• Whole nutmeg and white and black peppercorns — organic, non-irradiated, ground fresh

• Single-estate extra virgin olive oil — harvest-dated within the past year, in dark glass

• Baja Gold sea salt for cooking; fleur de sel de Guérande or Maldon for finishing

Storage

• Cooked halibut: Refrigerated up to 2 days. Best fresh, since reheating dries out the delicate flesh. Flake it cold over salad instead

• Cauliflower purée: Refrigerated up to 4 days. Rewarm gently on the stovetop with a splash of water or broth

• Grilled asparagus: Refrigerated up to 3 days

• Lemon-basil oil: Refrigerated up to 4 days. An honest note: homemade oil with fresh garlic should always live in the fridge and be used within 4 days. Let it come to room temperature and stir before using

Leftover transformations: Flake cold halibut over greens with grilled asparagus and a drizzle of lemon-basil oil for a next-day lunch; fold leftover purée into pastured eggs for a creamy scramble; chop grilled asparagus into a frittata.
