Freshly squeezed calamansi, a little sugar, and cold water — a tart-sweet Filipino citrus drink that comes together in minutes and disappears just as fast on a hot day.
Calamansi juice is the everyday Filipino answer to lemonade — brighter and more floral than lime, less sweet than orange, and unmistakably its own thing. It's poured at merienda, at parties, and at pretty much any gathering where a pitcher of something cold needs to be on the table.
Unlike lemonade, calamansi juice doesn't need much sugar to come alive — the fruit's natural sweetness does a lot of the work, so the sugar is there to round out the tartness rather than mask it. Making a quick simple syrup first, instead of stirring sugar straight into cold water, is what keeps the finished drink from tasting gritty or unevenly sweet.
No fresh calamansi on hand? Bottled calamansi juice concentrate from a Filipino or Asian grocery store works well — just cut back on the added sugar since most concentrates are pre-sweetened.
Bottled calamansi juice concentrate, sold at most Filipino and Asian grocery stores, works well — just cut back on the added sugar since most concentrates are pre-sweetened. In a pinch, a mix of lime juice with a splash of orange juice gets you reasonably close to the flavor.
Roll each calamansi firmly on the counter with your palm before halving it — this breaks down the membranes inside and makes squeezing easier. Squeezing cut-side-up into your palm first also lets you catch the seeds before they fall into the juice.
Fresh calamansi juice concentrate (before diluting with water) keeps for about a week refrigerated in a sealed container. Once mixed into a full pitcher of juice, it's best within 2 to 3 days for the brightest flavor.
