In 1837, she published anonymously her Kogebog for smaa Huusholdninger, the first of several cookbooks she wrote for small households, young girls and soldiers in the field.
[1][2] Born on 12 June 1781 in Copenhagen, Mangor was the daughter of the assessor Andreas Bang (1740–1801) and Anna Sybille Terkelsen (1746–1822).
Titled Kogebog for smaa Huusholdninger (Cookbook for Small Households), the original edition contained no reference to the author.
[2] Later works include En Bedstemoders Fortællinger for sine Børnebørn (A Grandmother's Tales for her Grandchildren, 1843), Kogebog for smaa Piger (Cookbook for Young Girls, 1848), a novel titled Tante Cousine (1852) and Kogebog for Soldaten i Felten (Cookbook for Soldiers in the Field, 1864), donating thousands of copies to the army as a token of her patriotism.
The work's popularity was a result of its inclusion of reliably presented recipes for the common dishes of the day, updated in later editions to reflect changes in cooking developments from the open fire to the oven.
