What are yellow tomatoes?
Yellow tomatoes are a yellow-colored type of tomato. They are the exact same species as regular red tomatoes, just a different color. Botanically speaking, yellow tomatoes are a fruit, a berry to be more exact, but a culinary vegetable. What makes them yellow instead of red is a class of organic yellow pigments called xanthophylls (e.g. lutein, zeaxanthin).
The pigments develop naturally in yellow tomatoes, presumably as a natural mutation that occurred early in the fruit’s history. In fact, yellow tomatoes are documented to have been brought to Europe from South America as early as the 1500s. Unlike yellow tomatoes which occurred naturally, blue tomatoes as well as black tomatoes are genetically modified.
What do yellow tomatoes look like?
Yellow tomatoes come in many forms and sizes and almost as many varieties as red ones. There are yellow cherry tomatoes and yellow grape tomatoes, with special varieties such as round yellow baby tomatoes and pear-shaped yellow pear tomatoes.
There are regular size, perfectly round yellow tomatoes and large ribbed beef varieties such as the yellow Beefsteak tomatoes. The skin is thin, glossy and smooth, and ranges in color from pale yellow to golden yellow to yellow-orange. The flesh is soft, but firm and the juice pale yellow to colorless. Special varieties such as yellow and red or yellow and orange-striped tomatoes or yellow tomatoes with purple or blue shoulders also exist (see pictures below).
Note: Yellow tomatoes are not just unripe red tomatoes. They are an entirely different variety from red and are perfectly ripe when they are a uniform yellow color. But both yellow and red tomatoes start out green when unripe and turn yellow and red, respectively, when ripe. Find out more about what are yellow tomatoes.
