Method
Combine the farro and stock in a large, heavy saucepan over medium heat. Cover and simmer, stirring occasionally, until the farro is tender, 45 minutes to an hour, or about half the time if you are using semi-pearled farro.
Meanwhile, heat the olive oil in a skillet over medium-high heat, then add the chopped green onions and saute for 5 minutes, or until the onions start to soften. Stir in a couple pinches of salt. If you have a hand blender, transfer to a small bowl and lightly puree them, but don't go overboard. Alternatively, puree them in a food processor. After a pulse or two, they will start to get nice and creamy, but you want to maintain some nice big chinks of green in there as well.
When the farro is nearly cooked, stir in the asparagus. Let the pot simmer for another couple of minutes, until the app0aragus is a vibrant green. Some stock will still be visible in the pot. This is fine; the farro will continue to absorb the liquid once removed from the heat. Stir in the lemon zest, walnuts, and the 1/2 teaspoon salt. Add more salt to taste if needed.
ladle into bowls and garnish with a dollop of Crème Fraîche, a dusting of Parmesan cheese, an d a hearty spoonful of green onions.
Serves: 4 to 6
