Bubble tea pearl mold

thingiverse

This is a press/mold that I designed to avoid having to roll tapioca pearls when making bubble tea at home. In my opinion, the 8mm pearls have the perfect size. You can easily edit the mold and increase the amount of pearls by raising the size_x/y values. The top and bottom parts are both included in the press.scad file. Simply switch the boolean from true to false to generate a different STL file. ## Print Settings I printed my mold at 22% infill using a gyroid pattern with PLA at 200C. ## Usage: My tapioca pearl recipe consists of 3 parts tapioca starch and 1 part warm/boiling water. Depending on humidity, I sometimes use a 9:4 or 9:5 ratio. I find it easier to knead the dough if it is sifted first. To prevent stickiness, wrap both halves in plastic wrap and lightly cover them with tapioca starch. When putting the pearl paste/dough in the mold, make sure it's not too thick - around 5-8mm, depending on the size of the mold. You may need to add more water than usual to the tapioca starch/water mix to get the dough to flow smoothly. Be careful not to make it sticky. Once pressed, the pearls should break apart easily. To cook the pearls, submerge them in boiling water or a water/sugar mix until they turn translucent or have the right mouth-feel (about 20 minutes for me). The amount of water and sugar doesn't matter, but all the pearls should be submerged before they start floating. Brown sugar tastes better. You can store the pearls in the water/sugar mix if you like. They're best consumed within 24-36 hours or they'll harden. You might be able to reheat them slightly.
