Beautiful nasturtium flowers, in shades of saffron, russet, and burgundy, can also be ground into a paste and folded into softened butter to make a versatile compound butter. Chilled slices add bright flavor and a pop of color when set to melt atop pan-seared fish.

PAN-SEARED HALIBUT WITH NASTURTIUM BUTTER

Serves 2

Takes about 15 minutes to make.

Ingredients

  • 2 6-ounce halibut fillets, skin on
  • Sea salt
  • 1 Tbsp mild olive oil
  • Half a lemon
  • Nasturtium butter, chilled (see recipe below)

Instructions

  1. Season fillets with salt on both sides.
  2. In a large flat skillet over high heat, pour olive oil and tilt pan to coat.
  3. When oil smokes, add the fish fillets, skin side down.
  4. Cook until seared, about 6 minutes, then turn and sear the other side, about 3 more minutes.
  5. Reduce heat to medium and cook until the fillets are just opaque in the center, about another 4 minutes depending on thickness.
  6. Transfer fillets to plates, squeeze a bit of lemon over and top with a ½-inch-thick slice of nasturtium butter.

NASTURTIUM BUTTER

Makes about 8 ounces

Takes about 15 minutes to make, plus chilling time.

Ingredients

  • 1 packed cup fresh nasturtium blossoms
  • 1 stick (8 oz) organic sweet butter, softened

Instructions

  1. Pick petals from nasturtium blossoms and gently brush away any critters or dirt.
  2. Transfer the petals to a mortar and use the pestle to grind them into a paste.
  3. In a small bowl, combine the paste with the butter and use a small spatula to mix well.
  4. Scoop the butter onto a piece of plastic wrap or parchment paper and roll it into a small log, slightly shorter and fatter than a stick of butter. Twist the ends to seal.
  5. Refrigerate until cold and firm. Compound butter may also be stored in the freezer for several months; in the fridge for several days.
