Method

• 1.
  Soak dates in a bowl of warm water for 10 minutes, then drain and roughly chop. Set aside.
• 2.
  Meanwhile, peel and segment oranges, then squeeze the juice from the remaining flesh. Transfer segments and juice to a small saucepan over medium-high heat with honey cinnamon, cardamom, cloves, and 2 tbs water. Bring to the boil, then reduce heat to medium-low and cook for 12-15 minutes until syrup has thickened and reduced. Strain syrup through a sieve and set aside to cool completely. Reserve orange segments and discard any remaining solids.

• 3.
  Whiz the avocado, cocoa powder, and reserved dates and syrup in a food processor until smooth and creamy. Spoon into four 125ml serving glasses and chill for at least 1 hour to firm up.
• 4.
  Serve mousse chilled, topped with orange segments, pistachios and cocoa nibs, if using.
