Cook the sweet potatoes with sugar, glucose, water, and curry powder. Strain the potatoes, mash them and pour the resulting purée through a strainer. Leave to cool and add the Sabayon. Put in a siphon with one or two gas cartridges. Refrigerate for 2-3 hr.
Bring water and sugar to the boil. Add softened cream cheese as well as the cream. Blend or process (Paco-Jet).
Boil together water and sugar.
Finely slice sweet potatoes and leave to soak in syrup. Place the slices between two sheets of Silpat (non-stick baking liners) and dry in the oven at 120°C for 2 hr.
Make a sauce with sesame oil and the rest of the syrup. Mix with the micro salad.
Using a siphon, garnish the plate with sweet potato mousse (espuma). Place the seasoned salad in a spoon, top with a dollop of cream cheese sorbet. Garnish mousse with sweetened potato crisps. Serve with mango coulis.
