Tomato is a fruit, right - so yes, ok on pizza, salad, etc. I am not a fan of cooks who use adventure for the sake of adventure as a substitute for good basic instincts with combining flavors. Sometimes there is a really good reason why no one has done something before. Still, blending flavors, including fruit, can be a good thing - I had marinated strawberries on a green butter lettuce salad and it was ok - not great, but a pleasant flavor. I am told German cooking commonly involves sweet/savory mixes; I don’t do a lot of German cooking. Riesling is kind of an anti-wine to my palate. The argument for just eating the fruit straight up is that you can focus on that flavor - I usually prefer that. I buy blueberries and just run them under the water and eat them right out of the container. Just love them. I don’t need yogurt or sugar or salad or oatmeal.
