Troubleshooting
Dough cracks when shaping.
Add a little more water and knead until smooth.
Dumplings fall apart when boiling.
Dough may be too wet; add more potato starch and reshape.
Dumplings are dense, not chewy.
Ensure potatoes are mashed very finely and dough is not too dry.
Sauce is too spicy.
Reduce chili powder or use a milder variety.
