UK suppliers describe the cream sausage tomato as a heritage or heirloom tomato, however in the USA there is a very similar looking tomato, bush variety, yellow, paste developed by the master of tomatoes Tom Wagner in 2004. I am assuming they are the same, however it makes it as heirloom as my old Nokia 8210 mobile phone.
When compared to our continental cousins such as the French and Italians, American food often has a poor reputation in Europe, fairing even less well than my homeland of Britain. From chlorine washed chicken and genetically modified crops (both of which are banned in Europe) to the Macdonaldalisation of the world to the “Supersized” generation. However Amish paste is one supersized American import that is seriously worth looking at.
