Tagliatella should be 8 mm wide, after cooking, when served on the table.
It was solemnly declared by the Bologna Delegation of the Accademia Italiana della Cucina and deposited with notarial deed on April 16th 1972 at the Chamber of Commerce of Bologna, in Palazzo della Mercanzia.
This size is 1/12,270 of the height of the Asinelli Tower in Bologna!
It has been reproduced in a golden sample, held in a casket, with the following writing: 8 mm, size of the Tagliatella - Accademia Italiana - 1972. The sample is jealously held in the Palazzo della Mercanzia in Bologna, as a testimony and as protection of the glorious traditions of the Bologna cuisine.
