Stir, strain in coupe. Garnish.
To make the Oleo-Saccharum: microplane some clementines in a bowl and add sugar to cover. Steep overnight. Add a bit of boiling water. Steep overnight. Strain. Press liquids. Bottle.
The same ratios work well with brandy, lemon oleo, bigallet china.
Seems spirit+amaro+ oleo make a good deal.
