Soak the gelatine in ice-cold water.
Start cooking the garlic and shallots in a little olive oil, then add the sherry vinegar and the three vegetable coulis.
Mix until smooth in the blender and season to taste with salt and pepper.
Pass through a fine sieve.
Heat some of the coulis, add the pre-soaked gelatine and place on ice-cold water.
Beat the whipping cream to yoghurt thickness, add a small portion to the set mixture and mix until smooth.
Fold in the remaining cream.
Fill silicone moulds.
Leave to set in the refrigerator and freeze in the blast chiller to at least -20°C to be able to turn them out easily.
