Ingredients

2 carrots, coarsely chopped

2 celery stalks, coarsely chopped

1/2 medium onion

4 sprigs fresh thyme

4 sprigs fresh flat-leaf parsley

1 tablespoon whole black peppercorns

8 ounces yellow split peas

4 cups water

2 teaspoons coarse salt

1 tablespoon fresh lemon juice

Extra-virgin olive oil, for drizzling

1 small red onion, thinly sliced

1 tablespoon plus 1 teaspoon capers

Freshly ground pepper, to taste

1/2 baguette, cut into 1/2-inch-thick slices and toasted

Sugar snap peas, baby carrots, patty pan squashes, and zucchini flowers, for serving

Preparation

Make the bouquet garni: Place the ingredients on a piece of cheesecloth. Tie into a bundle with kitchen twine.

Make the spread: Combine split peas, water, 1 teaspoon salt, and the bouquet garni in a medium saucepan. Bring to a boil. Reduce heat, and simmer until split peas are tender, about 45 minutes. Discard bouquet garni. Reserve 1/2 cup cooking liquid. Drain split peas, and let cool slightly in strainer, about 10 minutes.

Puree split peas, lemon juice, remaining teaspoon salt, and 1/4 cup plus 1 tablespoon reserved cooking liquid in a food processor until completely smooth. If the mixture is very thick, add more liquid. (Spread can be refrigerated in an airtight container for up to 1 week.)

Before serving, drizzle with oil, top with onion and capers, and season with pepper. Serve with toasts and crudites.
