• Make-Ahead

Ingredients

1. 1 pound medium zucchini
2. 1 large baking potato (3/4 pound), peeled
3. 1 small onion (4 ounces), peeled
4. 1/2 cup matzo meal
5. 1 large egg, lightly beaten
6. 1 teaspoon fresh lemon juice
7. 1 1/2 teaspoons salt
8. 1/2 teaspoon freshly ground pepper
9. Vegetable oil, for frying
10. 1/2 cup sour cream
11. 1/2 cup red pepper jelly
12. 3 ounces skinless smoked trout fillet, coarsely chopped
13. 2 ounces golden trout roe (see Note)
14. 3 scallions, green parts only, thinly sliced

Directions

1. Halve the zucchini crosswise. Cut the zucchini flesh off the seedy center and coarsely grate it in a food processor. Or grate it on a box grater until you reach the seedy center. Discard the center. In a food processor or on a box grater, coarsely grate the potato and onion. Transfer the grated zucchini, potato and onion to a colander and squeeze dry. Let stand for 2 minutes, then squeeze again. Transfer the vegetable mixture to a large bowl. Add the matzo meal, egg, lemon juice, salt and pepper and stir to combine.
2. In a medium skillet, heat 2 tablespoons of vegetable oil until shimmering. Drop packed teaspoons of the zucchini mixture into the skillet and flatten them with the back of a spoon. Cook the latkes over moderately high heat until the edges are golden, about 1 1/2 minutes; flip and cook until golden on the bottom, about 1 minute. Drain on paper towels. Repeat with the remaining zucchini mixture, adding more oil to the skillet as needed.
3. Arrange the latkes on a platter and top each one with a dollop of sour cream and a little red pepper jelly, smoked trout and golden trout roe; sprinkle with the scallion greens. Serve warm.

Make Ahead

The fried latkes can be kept at room temperature for up to 4 hours. Reheat them on a dark baking sheet in a 375° oven for about 5 minutes, or until warmed through and crisp.

Notes
