About Fonda Las Cazuelas

Fonda Las Cazuelas is a small, independent kitchen-math site built around one job: scaling recipes without errors. A fonda is a practical neighborhood kitchen, and cazuelas are the clay pots that turn one base recipe into food for two people or twenty, depending on the day. That is the promise we care about: one recipe, any batch size.

What this site is

A free scaling calculator with an exact-fraction engine, plus field guides that explain the kitchen math in the open — halving charts, gram tables, the rules for salt and leavening at scale. The calculator and the guides use one shared measurement standard, published in full on the methodology page, so a number you see in a guide is the number the tool computes.

What it isn't

It isn't a recipe site — we don't publish or scrape recipes, and the text you paste into the calculator never leaves your browser. It isn't a nutrition or medical resource. And it isn't a content farm: every guide is researched and written for this site, with worked examples we've actually checked against a scale.

Who writes it

Guides are written and maintained by the Fonda Las Cazuelas Kitchen Desk — the site's small editorial team — with every chart cross-checked against the engine's test cases before publication. We are home cooks with calculators, not credentialed food scientists, and we write within that lane: measurement math, scaling rules of thumb, and honest caveats where physics outruns arithmetic.

Corrections

If a conversion on this site is wrong, we want to know more than we want to be right. Write to hello@fonda-las-cazuelas.com with the page and the number in question; verified corrections ship quickly and get noted on the methodology page.
