Jus Lemon Cui - Calamansi Juice

Lemon cui or calamansi is mainly used in soto or soup, much like how we use jeruk limo (kaffir lime) or jeruk nipis (regular lime). This tiny citrus with bright orange pulps are also commonly made into refreshing juice. They are really flavorful and super acidic, so a little bit goes a long way. A rough guide would be 3 to 4 calamansis per glass of water, plus 1 to 2 heaping tablespoon of sugar (you can use honey too ♥), then chilled or add some ice cubes and served cold. Easy right?

    What is the conversion of sugar to honey? Thanks

    • Anita Anita says:

      It would be about the same amount as sugar, but you can just adjust the amount to suit your taste.
