Ingredients
2 sheets frozen all-butter puff pastry, thawed in the fridge
1 egg
6 tablespoons (3/4 stick) butter
1 bunch ramps, whites chopped and greens sliced 1/2-inch thick
2 small to medium onions, chopped
3 cloves garlic, thinly sliced or chopped
2 or 3 ribs organic celery, finely chopped
4 or 5 small spring carrots, cut into 1/8-inch-thick slices
3 small to medium potatoes, finely diced
Salt and pepper
5 tablespoons all-purpose flour
8 cups poaching liquid (from poached chicken) or chicken stock
1/3 cup heavy cream (optional)
1 tablespoon Dijon mustard
1 cup fresh spring peas
1/2 bunch thin asparagus, ends trimmed, thinly sliced on an angle
3 tablespoons chopped fresh tarragon
3 tablespoons chopped fresh flat-leaf parsley
3 cups diced cooked chicken
Directions
Preheat the oven to 375°F. Line a baking sheet with parchment paper or use a nonstick baking sheet. Lightly roll out the puff pastry, then cut the pastry into shapes that reflect the shape and size of the dishes or bowls you wish to serve the stew in (I made little hearts this particular day). Beat the egg with a splash of water and arrange the cut pastry on the baking sheet. Brush the dough with the egg wash and bake to golden, 20 to 25 minutes.
While the pastry is baking, in a large pot, melt the butter over medium heat. Add the ramp whites, onions, garlic, celery, carrots, and potatoes; season with salt and pepper. Partially cover and let that cook until the vegetables are tender.
Sprinkle with the flour and stir to combine. Add the poaching liquid and cook, stirring well (really work the bottom of the pot to make sure you don’t get any roux sticking on the bottom), until thickened.
Add the cream if you want; I added the cream because the baby [Viv] really loves cream of chicken soup, but it isn’t really necessary—it’s gilding the lily. Add the mustard, peas, ramp greens, asparagus, tarragon, and parsley. Add the chicken and as soon as the peas heat through and the asparagus is tender-crisp, you’re ready to serve it up.
Ladle the chicken mixture into bowls and put the puff pastry up on top (the baby loved it).
