Spinach Bouillabaisse

Step 1

Bring a large pot of water to a boil while you prepare the spinach. When the water comes to a boil, salt generously and add the spinach. Blanch for 30 seconds and transfer to a bowl of cold water without draining the water from the pot. Measure out 2 quarts of the boiling water and set aside. Drain the spinach, squeeze out excess water and chop coarsely. Set aside.

Step 2

Heat the olive oil in a large, heavy soup pot or Dutch oven and add the onion and leek. Cook, stirring often, until tender, about 5 minutes. Add a generous pinch of salt and the garlic, stir over medium heat until the garlic smells fragrant, no more than a minute, and stir in the broth from the spinach, the potatoes, bouquet garni and salt to taste. Bring to a boil, add the saffron, and turn the heat to low. Cover and simmer 20 to 30 minutes, until the potatoes are tender but still intact and the broth is fragrant.

Step 3

Stir in the spinach, cover and continue to simmer for another 10 minutes. Add pepper, remove the bouquet garni, taste and adjust seasonings.

Step 4

Keep the soup at a bare simmer. Break each egg into the soup (I prefer to first break the egg into a teacup and then tip it into the soup). Cover and continue to simmer until the eggs are set, about 5 minutes.

Step 5

Serve the soup in wide bowls with an egg in each one. Sprinkle gruyere over each egg, and garnish if desired with toasted rounds of baguette or whole-wheat bread rubbed with garlic.
