How to use this tool

Enter the diameter of your wrapper (store-bought round skins are usually 9 cm). Pick thickness and filling. The card shows safe filling weight, the right fold, cooking time, and how long it survives in the freezer.

What this solves 茅聢楼?and what it doesn't

Dumplings burst for three reasons 茅聢楼?too much filling, wrong fold for the skin thickness, or skin rolled too thin. Most online recipes ignore the first two and only show one fold type. This tool ties the wrapper you actually have to a filling weight and fold that will not fail.

Who this is for

Anyone who has had dumplings burst in the pot. Beginners making their first batch of jiaozi from scratch. People converting Chinese-family recipes into weights their kitchen scale can read.

How to read the result

Filling weight is a maximum, not a target. A dumpling with less filling is easier to seal. If you are a beginner, use 80% of the number shown. For freezer life: 3 months is the safe commercial standard, but home freezers with frequent door-opening reduce this.

Honest limitations

Common questions

Why does my dumpling always burst? Either too much filling, skin rolled too thin, or water not at a rolling boil. Try cutting filling weight by 20%.

Half-moon or pleated? Half-moon is faster (good for beginners). Pleated looks better and holds more soup if the filling is wet.

Can I refreeze thawed dumplings? No. Cook them or lose them.
