As a side note, the leftover walnut crema disappeared quickly as Mr. B decided that it was great eaten like peanut butter- by the spoonfull!
Recipe from Orangette, adapted from A-16: Food + Wine
Serves 6 (as a side dish)
Ingredients:
Kosher salt
1 ½ cups Raw walnuts
½ cup plus 1 Tbsp. Extra virgin olive oil, plus additional to drizzle on top
1 small Red onion, diced (about 1 cup)
3 bunches Fat asparagus (about 30 spears, total)
1 block Pecorino Romano or Pecorino Tartufo
Lemon wedges, optional
Directions:
Prepare the Walnut Crema
Place a medium pot of salted water over high heat. Bring water to a boil. Add walnuts to the pot and blanch until they are tender in the middle (about 10 minutes). Reserve 1/4 cup of the cooking water for later, and then drain the rest of the water off of the nuts.
Place a small skillet over medium heat. Add 1 tablespoon of olive oil and warm the oil briefly. Add in the red onion along with a pinch of kosher salt. Cook the onion gently until softened and golden brown, about 7 minutes. Set onion aside off the heat.
Using a food processor, place the walnuts, reserved cooking water, and onion into the bowl of the processor. Process until the contents are creamy in appearance. Taste the mixture and then add generous amount of salt, tasting as you add it to ensure the right balance of salt. Turn the processor back on, and while it is running slowly pour in 1/2 cup of olive oil until it is well blended. At this point the contents should resemble a creamy hummus in texture. If things look too thick, add a bit of water to thin it out. Taste the mixture one more time to make sure that it does not need additional salt, and then transfer it into a separate container with lid. You can cover the crema and keep it at room temperature or you can store it in the fridge for a few days before serving (just bring it to room temperature when you are ready to use it).
Prepare the Asparagus
Preheat the oven to 500°F. Line two baking sheets with aluminum foil.
Rinse the asparagus spears, and snap off the tough ends (about 1″ from the thick bottom). Lay asparagus in a single layer on the baking sheets. Lightly drizzle the spears with olive oil and sprinkle with a pinch of kosher salt. Use your hands to rub the asparagus around in the oil, making sure that all sides are well coated. Place sheets in the oven and bake for 8-10 minutes, or until asparagus is starting to blister and soften. While baking, shake the pan once or twice to roll the asparagus over and blister all sides of the spears.
When serving, spread the crema evenly across a large plate. Use tongs to transfer the asparagus spears on top of the crema while they are still hot. Quickly shave pecorino or tartufo on top of the asparagus, letting the residual heat of the spears slightly melt the cheese. Drizzle a little bit of olive oil over the entire dish. Squeeze the lemon juice over the top of the dish if so desired, and serve immediately.
