Salad tomatoes is another term for simple round tomatoes. Both terms mean 70% of all tomato varieties. These are round fruits with a diameter between 4.5 and 6.5 cm, weighing 60-100 g.
The name came about because these tomato varieties deliver the classic tomato for a fresh tomato salad. You can find round tomatoes in all colours, and they have a rather sweet-sour aroma.
