FAQ

What ingredient text formats are supported?

Both '2 cups flour' and 'flour 200g' work, with units such as g, kg, ml, tbsp, tsp, cups, oz and lb, fractions like 1 1/2 or ½. Lines without numbers (headings, notes) are kept as-is.

What dishes is the salt back-calculation useful for?

It works for soups, stews, stir-fries — any dish where you mix seasonings into a total ingredient weight. Especially useful for smart cooker recipes.

What density data is the unit converter based on?

Standard culinary density data from cooking references. Ingredients without available density data are kept as-is in the output.

Can I use the results in other apps?

Yes — export as Text, Markdown, or JSON. Paste directly into Notion, Google Docs, or any note-taking app.
