As you're rolling the larger piece of dough may start drying out. Not to worry just add a few drops of water on the surface and knead again.
It's handy to have a damp paper towel and a bowl of the starch to help rolling.
u will need to roll the ball on the damp towel because it's drying and won't roll properly. If the towel is too wet you need to lightly roll it in the strach to fix that.
Cooking: bring water to boiling then add pearls. Stir. When they float they are half way cooked. I like mine chewy so I only continue cooking for 10 more min. But you can leave it up to 20-25 min.
Then quickly drain pearl and put them in an ice bath. Cook your pearl just before making your tea :)
Hope you enjoy my first guide. Don't hesitate to ask questions. 😘
