Hi i noticed it is very difficult to blend the tapioca into hot water on the pot. Basically it creates little assemblements and it doesnt dissolve. What should i do?

What do you mean by "parts". Can you use teaspoon or tablespoon please? I don't understand
@giestas2 жыл бұрын
When you see a recipe expressed in 'parts' that means you are looking at the recipe 'ratio', which is supposed to help you scale the quantity up and down. Example: let's say you don't have measuring spoons at home and all you have is a small coffee cup. If the ratio called for 3:1:1:1, that would be 3 cups of water, 1 cup of starch, 1 cup of vinegar, 1 cup of glycerin. Then, let's say you wanted a bioplastic that was double the size. Following the same ratio 3:1:1:1 all you need to do is double the numbers, so that would be: 6 cups of water, 2 cups of starch, 2 cups of vinegar, 2 cup of glycerin.
