Banana and hazelnut chocolate pots

Method

1. Mash the bananas in a bowl, then mix in the cream, sea salt flakes and sugar. Pour into a pan and heat very gently, stirring constantly, until steaming. Scatter in the dark chocolate, then take off the heat and stir to combine. Transfer to a food processor and whizz until smooth (or use a stick blender). Strain through a sieve into a jug, discarding any strainings, then share among 8 small glasses or pots.
2. Cover each with a piece of cling film, leave to cool completely, then chill (see make ahead).
3. Meanwhile, toast the hazelnuts in a medium oven, then very finely chop or whizz to fine crumbs in a food processor with the remaining tablespoon of sugar. Keep somewhere cool in an airtight container or bag until needed.
4. To serve, scatter some of the sugared hazelnuts over the top of each pot and serve. Put the rest in a bowl for people to add themselves.
