VESELA MIHAYLOVA AND VERONIKA KRENN - PRAZLAB

The traditional Austrian cake Linzer is considered the oldest cake recipe in the world. It was mentioned for the first time in a cookbook in 1653. To this day it is not clear exactly where its name comes from. Nevertheless, all tourist brochures in Linz, the capital of Upper Austria, declare the city to be the official homeland of the famous cake.In 2011 the local municipal council published the statistical data on the city for the last years. According to the mayor of Linz, the city lying on the Danube is becoming an increasingly popular place to live. Despite the economic crisis, the urban development doesn’t stop; new buildings, parks and green areas are built and the birth rate reaches record levels.The Linzer Torten Diagramm Project studies the social and demographic situation in the city from the perspective of the female citizens. For this purpose Vesela Mihaylova and Veronika Krenn prepare nine cakes to a unique recipe, generated according to the statistical data of year 2003 - 2011.  The main products in in each recipe are calculated according to the number of women living in Linz, the unemployment rate, the difference between birth and death rates in women and the number of the private apartments for the respective year. Each of these indicators corresponds to the quantity of the main ingredients of the cake: flour, sugar, butter, jam and almonds.

Vesela Mhaylova (b 1979, Sofia) and Veronika Krenn (b 1987, Vienna) met in the university kitchen while doing their Master degree Interface Cultures at The University of Arts in Linz.Since 2012 they’re together under the name Prazlab, creating works based on the universal language of food, using cooking techniques and focusing on the act of eating. Their projects have been presented internationally, among others at The National Museum of Contemporary Art - Bucharest, Sonar Festival, Spain, Ars Electronica Festival, Austria; Goethe Institute Sofia and _V2, Institute for Unstable Media, Rotterdam. The duo was awarded Gabriele Heidecker Prize in 2014.
