Aerated raspberry mousse with herb sorbet and cocoa

Not yet rated

There are five separate elements to this knockout dessert from chef Chris Harrod, all of which can be made in advance. The frozen mousse, flavour-packed sorbet and cocoa soil work in perfect harmony, with crunchy shards of cacao nibs and a smooth raspberry purée providing contrasts in texture. If you're struggling to find all the herbs needed for the sorbet, Chris says you can substitute any you can't source with tarragon and chervil.

Method

1
Begin by making the raspberry mousse. Combine the sugar and purée in a pan and gently warm to dissolve the sugar. Remove from the heat and place 75g of the purée in a separate pan with the gelatine (squeeze the leaves to remove excess liquid before adding). Mix until dissolved and set aside. Pour the remaining purée into a shallow tray or container and place in the freezer
  • 50g of caster sugar
  • 250g of raspberry purée
  • 2 1/2 gelatine leaves, soaked in cold water
2
Once the frozen mixture has reached a slushy texture, remove from the freezer. Warm the gelatine and raspberry mixture until it reaches 40°C, then transfer to a mixing bowl with the whisk attachment and mix at high speed. Slowly drip the slushy mixture down the side of the bowl while the whisk is running. Once fully incorporated, allow to mix for a further minute, then pour into a shallow tray so the mixture is 2cm thick. Freeze until ready to serve
3
For the sorbet, bring the water, sugar and glucose to the boil, then remove from the heat and allow to cool. Reserve 25ml of the liquid, and place the rest into a blender with the herbs. Blitz at high speed until you are left with a smooth green liquid. Pour the mixture through a fine sieve into a bowl, pushing the pulp with the back of a ladle

  • 112g of caster sugar
  • 37g of glucose syrup
  • 25g of sorrel, ideally lamb's sorrel, washed
  • 12g of tarragon, washed and picked
  • 10g of lemon verbena, washed and picked
  • 5g of lemon balm, washed and picked
  • 5g of spruce tips
4
Warm the reserved liquid, add the gelatine and stir until dissolved. Combine with the herb liquid, then churn in an ice cream machine according to the manufacturer’s instructions
  • 1 gelatine leaf, soaked in cold water
5
For the cocoa soil, place the flour and almonds into a blender and blend together into a coarse powder. Transfer to a mixing bowl with a paddle attachment, add the sugar and mix well. Slowly add the butter and mix until it resembles fine breadcrumbs. Pour out onto a baking sheet and loosely bring together before rolling to a 1mm thickness. Freeze
6
Preheat the oven to 170°C/gas mark 3. Place the frozen soil into the oven and cook for 10 minutes until light golden. Remove, allow to cool, mix in the cocoa powder and reserve in an airtight container
7
For the cacao nibs, place the sugar and glucose into a heavy-based saucepan and heat to 160°C. Remove from the heat and mix in the cacao nibs and butter. Pour out onto a silicone sheet, cover with greaseproof paper and use a rolling pin to roll the mixture out as thinly as possible. Allow to cool, then break into shards and reserve in an airtight container
  • 25g of caster sugar
  • 20g of glucose syrup
  • 24g of cacao nibs
  • 2.5g of unsalted butter
8
Make the raspberry purée by blitzing the raspberries and caster sugar in a blender until smooth. Thicken with the Sosa Gel Cream then pass through a sieve to remove the seeds. Reserve in a squeeze bottle
9
Now you have all the elements of the dessert and are ready to plate. Remove the frozen mousse mixture from the freezer and cut out 4 circles 7cm in diameter. After 5 minutes they will have defrosted and become soft and airy in texture
10
Place a raspberry mousse in the centre of each plate. Take a spoonful of cocoa soil and scatter over the mousse, then arrange 5 raspberries around and intersperse with 5 dots of purée. Place a quenelle of herb sorbet on top of the mousse, then finish with 3 pieces of cocoa nib and scatter with the apple marigold leaves and sweet cicely flowers
