Boiled tapioca
As the name suggests refers to the tapioca which are boiled. You can use two cups of water per cup of chopped tapioca. You may use big chunks of peeled or unpeeled tapioca. These proportions are based on cooking with the pot cover on. This way, it will cook a little faster, use less energy, and perhaps retain more vitamins. You may also pressure cook the tapioca with or without salt for 2-3 minutes in boiling water.
Tapioca cubes
Turn the tapioca on its side and make a series of slices. Lay the tapioca on top of each other and make a series of lengthwise slices, (½ inch slices for smaller cubes, 1 inch slices for larger cubes. Make a series of ½ inch or 1 inch crosswise cuts through the tapioca and it will fall away into cubes.
