Slender stalks of green garlic and tender spring onions are fleeting seasonal delicacies that should be snatched up from your green grocers or farmers markets while they are still available.

Green garlic is a mild immature version of its grown up dried self, pulled from the ground before its bulbs form, and can be used now in fish dishes, light soups, sauces, and relishes such as the one featured here.

Spring onions are simply yellow, white or red onion youngsters; slim and delicate, mild and sweet.

Pair these two kids with the puckery flavors of blood orange and Meyer lemon and you've got a mouthwatering topping for a thick mild white fish like halibut. Cod, rockfish and sablefish will work just as well, but may take less time to roast depending on their thickness.

The cooking method used here is fast and easy.  Prepare the relish while the halibut is roasting in the oven; they will both be finished at the same time, ready to serve in about one-half hour from prep to plate.

A perfect springtime weeknight offering.

Roast Halibut Fillet with a Relish of Blood Orange, Meyer Lemon, Green Garlic and Spring Red Onion

Christine's original recipe
(print recipe)

Ingredients:

1-pound piece of halibut fillet

1 large Meyer lemon

1 small blood orange

1-2 tablespoons olive oil

3/4 teaspoon gray salt with herbs (sel gris aux herbes)

2 sprigs fresh oregano plus 1 tablespoon fresh oregano leaves, chopped

1/3 cup dry white wine

1 green garlic stalk and 1 spring red onion stalk

Halibut Preparation:

Preheat oven to 375 degrees.

Oil the bottom of a ceramic baking dish. Set aside.

Rinse fillet under cold water and gently pat dry.

Place fillet in baking dish, skin side down (skin removed) and rub the top with olive oil.

Sprinkle the fillet with the herb salt and cover the top of the fish with lemon slices. Reserve the remainder of the lemon.

Lay the oregano sprigs over the lemon slices.

Roast for 15 to 18 minutes or until the fish is cooked through but still very moist. It should be springy when pushed with your finger.

Meanwhile ...

Relish Preparation:

Wash both the green garlic and the spring onion stalks. Remove the outer layer of skin from each, slice off the root ends and thinly slice each one crosswise until you reach the neck.  (The necks may be saved for soup stock.)

Using a sharp knife and working over a bowl to catch the juices, remove the skin, seeds, white pith and membrane from the blood orange and the remainder of the Meyer lemon. Chop each citrus separately, reserving juices.

Heat a skillet over medium low and add 1 teaspoon or so of olive oil.

Sauté the green garlic and spring onion slices for about 1 and 1/2 minutes, stirring to separate the rings, until they are softened but not browned.

Add both chopped citruses and their juice to the pan, stir and sauté 2 minutes more, stirring frequently to prevent sticking.

Add the white wine, stir, turn the heat up to medium high and cook until the liquid is reduced by one half.

Stir in the chopped oregano and continue cooking until the pan is almost dry, 1 minute more.

You may have to adjust the heat as you go along to prevent the relish from burning.

Remove the pan from the heat.

To serve, remove the oregano sprigs and lemon slices from the roast halibut and slice the fish into serving size pieces.  Place on warm plates, top with the relish and a few more sprinklings of herb salt.

Enjoy!
