Origin
Costoluto Genovese is an Italian heirloom that originated in the Riviera region and was long popular in Piedmont's tomato-sauce industry; 'Costoluto' means 'ribbed' in Italian. Amy Goldman traces its introduction to North America to 1985, via Le Marche Seeds International and Redwood City Seed Company. It is deeply lobed and pleated, so much so that a cross-section looks like a flower, and its acidity is high by modern standards, which is why it holds its character through long cooking where sweeter varieties turn flat.
