Method · 35 min
  1. Wash all leaves, pat them dry and chop them roughly.
  2. Peel onion, dice it finely.
  3. In a heavy-bottomed stock pot, melt butter. Add diced onion and sauté over medium heat for 5 minutes, until lightly golden.
  4. Add chopped leaves with a pinch of salt, combine with a spatula. Stew under a lid for around 3-5 minutes.
  5. Pour broth in, stir and bring to a near-boil. Reduce the heat (so that the soup just simmers), cover with a lid and cook for 10 minutes.
  6. [Optional] Using a slotted spoon, remove around one-fifth of the leaves and into a bowl. Set aside.
  7. Blend soup with immersion blender until smooth. Alternatively, if using a food processor, allow the soup to cool down first, then move it over to the device's container, blend until smooth and return to the pot.
  8. [Optional] If you removed one-fifth of the leaves, now it's the moment to return them to the pot.
  9. Add 0.5 teaspoon of salt, 1 teaspoon of lemon juice, a pinch of ground pepper and 1 teaspoon of sugar. Stir and have a taste. Is it too sour for your liking? Add a touch of sugar. Is it not sour enough? Add more lemon juice.
  10. Bring the soup to desired temperature. Add cream and stir.
  11. Pour into individual bowls or soup plates. Garnish with eggs, lemon zest, fresh thyme and fried & crushed bacon. Serve immediately.
