Slice the rhubarb and add it into a mixing bowl with all the other ingredients and set aside – in the fridge preferably – for at least 30 minutes.
Preheat the oven at 400°, transfer the marinated fruit and their juice in a pan and bake for 20-25 minutes. Set aside to cool.
for the cream and the topping
In a saucepan add the agar powder, pour the creamer slowly stirring with a whisk. Switch on the flame and bring to boil.
Simmer for 5 minutes, going on stirring to prevent an uneven gelatinization and pour the mixture in a bowl.
When it’s cool put it in the fridge to set completely – it’ll become more compact than a pannacotta.
Cut it in pieces and blend it until smooth.
Pour alternatively some compote and some cream in 3 jars and top with almonds and pollen. I made the first divided in 3 layers – compote, cream, topping -, the second in 6 – compote, cream, topping, compote, cream topping – and the third pretty random, for a cowy result.
