Peel 3 citrons – avoid the bitter white pith.

Put the peel in a 1-quart bottle with 2 cups vodka and close it up for a week or longer.

Strain and discard the peels.

Add 1 1/2 cups extra-fine (baker's) sugar and shake or stir vigorously until dissolved.

Add 1 more cup of vodka. Shake until clear.

Close the jar and store it in a cool, dark place for at least 6 weeks.
