Calamansi juice is a beloved Filipino refreshment made from the small, tart citrus fruit known for its floral aroma and lively acidity.
Freshly squeezed calamansi is balanced with simple syrup and chilled water for a drink that is bright without being harsh.

Strain the juice after squeezing to remove seeds, then taste before adding all the syrup because calamansi varies in acidity.
Serving Suggestions
Serve very cold over ice with calamansi halves, or chill a pitcher for family-style meals and celebrations.

Recipe Notes
If fresh calamansi is unavailable, combine lime and mandarin juice for a close approximation.
