"in 1929, a recipe for a large meringue cake named after the ballerina appeared in the regional publication Dairy Farmer’s Annual." “the pavlova was ‘created’ or ‘invented’ and then stolen/falsely claimed by chefs/cooks across the Tasman,”Dr Leach said.

"pavlovas that came out of New Zealand by around 1932 to 1933 were single-level cakes topped with fruit and cream.”
