Cheese from Switzerland, Unterwalden
Bratkäse is a small, full-fat semi-hard cow cheese from Obwalden and Nidwalden, made to be melted. In valley dairies the milk is pasteurised, set with rennet at 32 °C, cut and warmed to 37 °C, pressed into tubes and brined; on the alps it is made by hand from raw milk. It ripens 6–10 weeks with a salt-water smear, and was once softened at the fire and scraped, like a small raclette. Made in 7 steps over 43 days – 2.3 months. The longest step, ripen with a salt-water smear, takes 42 days – 2.3 months (Kulinarisches Erbe der Schweiz / Patrimoine c…) and runs at 13–14 °C (Kulinarisches Erbe der Schweiz / Patrimoine c…). The dairy's own lactic culture does most of the fermenting.

Bratkäse is a small melting cheese of Unterwalden, ripened only 6–10 weeks where Valais raclette ripens 3–6 months. Valley dairies add water to the milk to slow its souring and let the pressed curd sour at 23 °C before brining.
Valley-dairy Bratkäse is made from pasteurised milk; alp cheese is made from raw milk. No safety study of this cheese was found.
Every number is labelled with how it is known. How this atlas is made
The inventory cites a possible 12th–13th century record from Muri monastery of cheese melted at the fire in Unterwalden. An 1836 regional survey lists it among Unterwalden's specialities, and the Swiss German dictionary of 1895 defines it as a small fatty cheese softened at a coal fire. The name Heikuhkäsli is linked to cheese made in the valley from leftover milk.
