Calamansi
Calamansi is a small, round citrus native to the Philippines, prized for its intensely tart, floral juice that functions as the backbone souring agent in Filipino cooking, much like lime does elsewhere in Southeast Asia.
How to buy
Look for calamansi that is firm, glossy, and heavy for its size; the skin is often green even when fully ripe and juicy, though some fruit ripens to orange. Avoid any with soft, shriveled, or moldy spots. Because each fruit is tiny and yields only a small amount of juice, buy in larger quantities than you would limes or lemons if a recipe calls for a significant amount of juice. Bottled calamansi juice or concentrate is a reasonable substitute when fresh fruit isn't available.
How to store
Fresh calamansi keeps at room temperature for a few days or up to two weeks refrigerated in a bag in the crisper drawer. Juice can be squeezed ahead and frozen in ice cube trays for months, which is a common practice in Filipino households given how labor-intensive juicing the small fruit can be. Whole fruit can also be frozen and thawed for juicing later with minimal quality loss.
Culinary profile
- Flavor
- Intensely tart and sour with a distinct floral-sweet undertone that sets it apart from lime or lemon -- less bitter than lime, with a brighter, almost tangerine-like perfume beneath the acidity. It's commonly used both as a souring agent and finished with a touch of sugar or salt to round out the sharpness.
- Texture
- The flesh is juicy but seedy and segmented much like a tiny orange, with a thin, easily squeezed peel. Most dishes use only the juice, discarding the pulp and skin, though the whole small fruit is sometimes halved and used as a garnish to squeeze at the table.
- Aroma
- A bright, citrusy perfume with a distinctive floral-tangerine note that's noticeably different from lime, making it instantly recognizable in Filipino dipping sauces and marinades.
How to prepare
- Juiced — Squeezed fresh for dipping sauces, marinades, and drinks; the small size means many fruits are needed for a useful amount.
- Halved as a table garnish — Served cut in half alongside soups and noodle dishes for diners to squeeze in themselves.
- Mixed with soy sauce (toyomansi) — Combined with soy sauce and chile as the most common Filipino dipping condiment.
- Sweetened into juice or cooler — Juiced and mixed with sugar and water for a tart, refreshing drink.
- Cooked into marmalade — Simmered whole with sugar into a tart-sweet preserve, peel included.

Substitutions
