Name: Marrowfat Pea Soup (Potage Saint-Germain)
Prep time: 15 min
Cook time: 30 min
Total time: 45 min
Yield: 4 servings
Ingredients: 2 leeks; 4 cups marrowfat peas (soaked overnight* with 1 tsp baking soda); 12 lettuce leaves, chopped; 12 spinach leaves, chopped; 1 teaspoon chervil, chopped (or fresh parsley); 1/2 cup butter; 2 teaspoons salt; 4 teaspoons sugar; 4 cups water; 1 cup green peas (baby peas are best)

1
Clean the leeks, removing the tough, dark parts and discard. Chop the leeks and place in a large saucepan with the drained marrowfat peas, lettuce and spinach leaves, chervil, half the butter, salt, sugar, and one-cup of cold water.
2
Bring to a boil, then lower the heat, cover, and simmer for 40-minutes.
3
Lightly blend, process or stick blender the contents of the pan (I leave some texture).
4
Add the remaining 3-cups of water, and stir until it comes to a boil. Remove from heat.
5
Heat the green peas in a small saucepan for a minute or two.
6
Add the remaining butter and the heated green peas to the marrowfat peas.
7
To serve, garnish with a swirl of yogurt and a small parsley sprig.
8
*I soaked mine for two-days (second day refrigerated) because I couldn't continue with the recipe due to a commitment. Didn't hurt the peas a bit.

Tips for the best results

Read through all the steps once before you start and measure out your ingredients first — it makes everything go more smoothly.
Taste as you go and adjust the seasoning before serving.
Avoid overcrowding the pan — cook in batches if needed for the best texture.
Let the dish rest for a few minutes before serving so the flavors settle.
Store leftovers in an airtight container in the fridge and enjoy within a few days.

Variations & substitutions

Use a neutral oil or a plant-based spread in place of butter for a dairy-free version.
Brown sugar instead of white sugar adds a deeper, more caramel-like flavor.
