This lime oleo is inspired by the oleo saccharum that forms the sweetening base for traditional punches. We used in in our March 2022 Irish Whiskey Cocktail History recipes.
INGREDIENTS
½ cup demerara or turbinado sugar*
Big pinch of kosher salt
½ cup water
5 grams zest, from 2-3 limes (about 1 Tbsp packed)
½ tsp citric acid
*Sugar in the Raw is an easy-to-find brand
Yield: approximately 6 ounces (¾ cup)
Make a demerara syrup (1:1 ratio) by combining ½ cup very warm water, sugar, and salt in a small saucepan. Stir to dissolve as much as possible, then heat on medium-low, stirring often until just completely dissolved. Let syrup cool. Zest limes. Combine syrup and lime zest in a blender or food processor. Blend for about a minute. Strain through a fine strainer and stir in citric acid. Label and store in fridge in airtight container. Keeps about 4 weeks.
