Oleo Saccharum
Sugar and citrus peels rest together until the sugar pulls out the essential oils and forms an intensely aromatic syrup, a classic punch base.
What it is
The name means 'oil sugar'. Sugar draws oils out of the peel through osmosis, without heat, so the aroma stays fresh and vivid.
It works with lemon, orange, grapefruit and mandarin. Dissolving it with citrus juice gives a 'sherbet' for punches.
Technique
Peel only the colored zest, avoiding the white pith, which is bitter. Mix with sugar, roughly equal weight sugar to peels, muddle lightly and rest covered.
After a few hours or overnight you'll see an oily syrup. Dissolve any remaining sugar with a little juice or water and strain.
Uses
Beyond punch, use it as an aromatic sweetener in Old Fashioneds or sours, and as a way to use peels from the juicing station.
