Native delicacies

The most common livelihood in Cainta is the making of native delicacies, which is largely a cottage industry. Its native desserts are among the nation's best. Dating back to the 15th century, it became the town's principal source of income for more than four centuries. Suman (rice cake wrapped in banana leaf), latik (boiled down coconut milk used for glazing), coconut jam and the famous bibingka, are but a few of the sweet delights that lure many visitors to this town. During the 20th century, Cainta dazzled the whole country when it baked the biggest rice cake ever and the town became known as the "Bibingka Capital of the Philippines". Bibingka is believed to have been adapted from the Indian cuisine, an influence from its Sepoy population. It comes from the Indian word bebinca also known as bibik, a dessert made of flour, coconut milk, and egg. The Philippine version is made of rice flour, coconut milk and salted duck eggs. Butter and sugar are used for glazing after cooking and before serving.
