Instructions

  1. Step 1: In a large pot, heat 1 tsp olive oil over medium heat. Add 100g thinly sliced carrots, 60g sliced leeks, and 100g sliced fennel. Sauté for 8 minutes until softened but not browned.
  2. Step 2: Add 750ml vegetable stock, 4 fresh thyme sprigs, and 1 bay leaf. Bring to a gentle simmer (not boiling) and cook uncovered for 25 minutes to infuse flavors.
  3. Step 3: Remove thyme sprigs and bay leaf. Stir in 1 tsp lemon zest until fragrant, then strain broth through a fine-mesh sieve into a clean bowl to ensure clarity. Return to pot and keep warm.
  4. Step 4: Just before serving, ladle broth into bowls and arrange 10 edible flower pieces and 10g microgreens on top, creating 'sparks' of color that float like festival light projections.
