Heirloom Squash Salad With Pepita Purée and Pickled Shallots

Preparation

1. Step 1

   Make the pepita purée: Heat oven to 350 degrees. Toss the pepitas with 1 teaspoon of the olive oil and roast until evenly browned, 5 to 7 minutes. Remove from oven and allow to cool.

2. Step 2

   Set aside 2 tablespoons of the cooled pepitas and place remaining pepitas in a blender with ¾ cup vegetable stock. Purée, drizzling in the remaining olive oil. Add lemon juice and season with salt and pepper to taste. Purée again, adding more broth if necessary for a consistency that is slightly thinner than tomato paste.

3. Step 3

   Cook the shallots: Bring a large saucepan of lightly salted water to a simmer. Meanwhile, in another large saucepan, combine the vinegar, sugar, cinnamon, cloves, bay leaf, star anise and red pepper flakes. Bring the vinegar mixture to a boil, reduce heat to low and cover and simmer for 5 minutes.

4. Step 4

   Prepare a large bowl of ice water. Blanch the shallots in the simmering water for 2 minutes. Using a slotted spoon, transfer to the bowl of ice water until cooled, then drain well.

5. Step 5

   Add the shallots to the vinegar mixture and simmer for 1 minute. Transfer to a bowl and allow to cool. Cover and refrigerate for up to 1 week; bring to room temperature before using.

6. Step 6

   Make the squash: Heat oven to 450 degrees. Fill a large pot halfway with lightly salted water and set over high heat to bring to a simmer. Prepare a large bowl of ice water. Spread paper towels across two baking sheets and set aside.

7. Step 7

   Using one type of squash at a time, blanch in the simmering water until tender but not falling apart. The delicata and butternut squash may take about 2 minutes; the kabocha may take slightly longer. Be careful not to overcook. As soon as the squash are blanched, remove with tongs or a slotted ladle and plunge into the ice water. When they have cooled, transfer to paper towels. Pat the squash with paper towels and allow to dry well; they will not brown when roasted if the surfaces are not dry.

8. Step 8

   Spread all the squash on 2 large baking sheets and season with salt and pepper. Drizzle with oil and rub the surfaces to coat well. Roast until the squash starts to color, 5 to 10 minutes. Meanwhile, spread the pepita purée on a large platter or individual plates, creating an even layer about ⅛-inch thick.

9. Step 9

   Transfer the roasted squash to the platter or plates on top of the purée, arranging it loosely to show off the different shapes. Disperse a cup of the drained pickled shallots among the squash. Garnish with the remaining pepitas, and serve warm.
