How To Make Limoncello
Prepare sugar syrup: Prepare a sugar syrup of at least 1 cup of water and 1 cup of sugar — bring the water to a simmer and stir in the sugar to dissolve; allow to cool.
→ You can play with the ratios of water to sugar. Start with 1 cup of water and 1 cup of sugar, taste the limoncello, and add additional sugar syrup gradually until you reach a flavor you like — up to 4 cups of water with 4 cups of sugar. More water will dilute the alcohol base, making a less alcoholic, milder, and smoother-sipping liqueur. More sugar will make a sweeter limoncello.
