  • Rainbow Trout
  • 1 cup hickory chips soaked in 1 cup wine for 30 minutes
  • 8 rainbow trout, preferably butterflied (8 ounces each)
  • Salt
  • Black pepper, preferably fresh ground
  • 4 green onions, cut into 2-inch pieces
  • 1/2 fennel bulb, cored and sliced 1/4-inch thick
  • 2 large tomatoes, each cut into eight pieces
  • 1 jalapeno, halved and thinly sliced
  • 1 lemon, sliced in rounds, 1/2inch thick
  • 1 cup white wine
  • 5 medium (2 1/2 pounds total) Mexican calabacitas (AKA tatume) or small zucchini
  • 3 large garlic cloves, peeled
  • 1 teaspoon coarse sea salt
  • 2 tablespoons olive or vegetable oil for zucchini mash
  • 2 teaspoons (loosely packed) chopped fresh cilantro (thick stems cut off), plus extra cilantro leaves for garnish
  • 1 egg yolk
  • 1 teaspoon prepared horseradish
  • 1 tablespoon fresh lime juice
  • 1/2 cup good-quality olive oil


1. Prepare the trout. Heat a gas grill to medium or light a charcoal fire and let it burn until the charcoal is covered with white ash and about medium-hot. Add the soaked wood chips to the grill. For a gas grill, place them in a smoker attachment box or wrap the chips in foil, poking holes to allow the smoke to escape; for charcoal, place them on the hot coals. Place the fish into a 13 x 9-inch baking dish. Season the fish inside and out with salt and pepper. Scatter the green onions, fennel, tomatoes, jalapeņo and lemon over the top of the fish. Pour the white wine over the fish and vegetable mixture. Once the chips start smoking, place the dish, uncovered, onto the grill. Close the grill and cook until the fish gives slightly under firm pressure of a finger, 15 to 20 minutes, depending on the heat of the grill.

2. Grill the zucchini. Pierce the zucchini all over with a fork. Finely chop the garlic. Sprinkle the salt over it and with the flat side of a knife mash together into a paste. Scoop into a bowl and mix in the oil. Coat the zucchini with the mixture and place on the grill, turning occasionally until tender and browned, about 25 minutes. Remove the zucchini to a cutting board and roughly chop. Scoop back into the bowl with the marinade and mash with a fork. Taste and season with additional salt, if necessary. If the zucchini mash is watery, strain before serving.

3. Make the aioli. Whisk together the cilantro, egg yolk, horseradish, lime juice and 1/2 teaspoon salt in a small bowl. Pour in the olive oil in a thin stream, whisking as you pour. Cover and refrigerate.

4. Finish the dish. Spoon the zucchini mash down the center of a large heated platter. Lay the fish (and the vegetables if you wish) on top of the zucchini. Spoon on the aioli and garnish with cilantro leaves and you're ready to serve.
