Inputs that match real kitchens

Numbers are calibrated for the equipment most home cooks actually own — gas stoves, instant pots, regular pots.

Notes, not just numbers

Every tool explains what the result means, what it doesn't mean, and where recipes from Chengdu, Guangzhou and Taipei disagree.

Honest about limits

No calculator replaces tasting. We say when to trust the number and when to ignore it.

What you won't find on generic cooking sites

Regional disagreement, shown clearly

The "right" congee ratio in Cantonese cooking is different from northern-style. We surface those differences instead of averaging them away.

Calibrated for English-speaking kitchens

Most Chinese recipes assume an electric pressure cooker and a specific gas range. We adapt for instant pots, slow cookers and weak apartment burners.

Translated, not just converted

"微辣" doesn't map to a single Scoville number. We give a range, plus a Western analogy (jalapeño, serrano) so you know what you're signing up for.

Honest limitations

We mark each tool with a confidence range. A sodium comparison calculator has more variability than a dumpling fold count.
