If you’re a tomato fan and think that tasting tomatoes all day sounds like the best job in the world, be warned; there is such a thing as tomato fatigue. “In all honesty, I’m kind of sick of eating plain tomatoes,” Klee says. He still loves cooked tomatoes, caprese salads, and the flavor of a raw tomato with a sprinkle of salt. But in flavor tests, the researchers must eat the fruits in their purest state. “To me, eating an unadulterated tomato isn’t so much fun anymore,” Klee says.
