AT A GLANCE
"This dish is made to be a side for the braised lamb," says Achatz. "The dates pair with the dark cocoa notes in the main dish, and the aromatic cardamom-date combination takes it to the Middle Eastern cooking of tagines and curries. But really what you have is a deconstructed mushroom, onion and fennel omelette."
|01||For date vinaigrette, blend ingredients with 80ml water and ½ tsp sea salt in a blender on high speed until very smooth (4-5 minutes). Thin to drizzling consistency with a little extra water if necessary and season to taste. Vinaigrette will keep refrigerated for up to 5 days.|
|02||Preheat oven to 175C. Trim the fronds from 3 fennel bulbs and reserve, then quarter the bulbs. Heat a roasting pan or very large sauté pan over medium-high heat, add oil, mushrooms, onion and fennel quarters, and cook without stirring for 3 minutes. Gently stir once and cook for another 3 minutes. Add butter, thyme and garlic, transfer to oven and cook, stirring twice, until mushrooms are just tender but with a little bite (8-10 minutes). Season to taste and keep warm.|
|03||Shave remaining fennel bulb on a mandolin and place in acidulated water (see note) to crisp.|
|04||Meanwhile, bring vinegar, 5 litres water and 2 tsp salt to a simmer in a large saucepan, stir vigorously to create a whirlpool, then crack eggs into the swirling water. Turn off heat, cover with a lid and stand for 6 minutes, then remove the eggs with a slotted spoon and drain on paper towels.|
|05||Transfer roasted mushrooms to a large serving dish, nestle eggs on top, drizzle with a little date vinaigrette, top with shaved fennel, season to taste, then scatter with fennel fronds and chives, and serve with remaining date vinaigrette.|
