Soak two types of mustard seeds in water for two days until they swell.
Whip up the mustard in a blender together with extra virgin olive oil, a small quantity of apple vinegar and one teaspoon of honey.
For the flower
Cook the hard part of the zucchini flowers in boiling water, taking care to keep the tender orange part out of the water.
Cold smoke the flowers and dress them with the mallow flowers, the wood sorrel leaves, salt, oil and mustard.
