What is Calamansi?
Calamansi, sometimes referred to as calamondin or Philippine lime, is a hybrid citrus fruit that's predominantly grown in the Philippines and other Southeast Asian countries. Picture a fruit that looks like a lime but with the size of a kumquat. That's pretty much what calamansi is.
The fruit itself has a diameter of about 2-4.5 cm and turns from greenish-yellow to yellow-orange as it ripens. If you're trying to imagine the taste, consider a blend of lemon and lime with just a hint of sweetness when fully ripe.
The calamansi meaning extends beyond its physical description, as it also represents a staple ingredient in many Southeast Asian cuisines.
