Start with peeling the Taro root. This vegetable root might irritate your skin; hence, it is advised to wear gloves or coat your hands with vinegar to prevent irritation. Use a vegetable peeler or knife to remove all the skin. Finally, slice the root into small cubes.

Add these taro root cubes, along with some purple sweet potato pieces, to a saucepan and cover with water. Steam them for around ten minutes or until the taro becomes tender.

Once Taro roots get boiled properly, you can add those chunks into the blender, followed by condensed milk and sugar.

Start blending the mixture until it becomes a smooth, creamy paste.

Moving ahead, add butter or oil, and Taro paste to a saucepan and stir regularly until the texture firms up. There should be no standing liquid, and the paste should be smooth and rich.
