According to this article a new type of tomato has been produced that won’t make your sandwiches go soggy. It has been produced by Tesco who claim it is the world’s first non leaking tomato. The tomatoes have been grown in Holland under a seed breeding programme that began in 1986. Unlike normal tomatoes which lose 8 per of their weight when sliced the non leaking variety loses less than one per cent of moisture meaning less juice ends up seeping into the bread of the sandwich. At 99p for four they are not cheap but if you are sick of eating soggy sandwiches then this might be the answer.
