Tomato Basil Frozen Yogurt

A couple weeks ago, I was preparing to leave for a 10-day trip, and realized that I had a couple extra tomatoes and yogurt in the fridge. I also had one of those supermarket basil plants growing in the window and I was pretty sure it would die while I was gone. What to do… why not frozen yogurt?

Well, one can actually think of a lot of reasons. "You could have made tomato sauce," said a colleague. True, but I just had two tomatoes. Not really enough for much sauce. There were other reasons not to do it too. Tomatoes aren't usually dessert. The idea sounds sort of odd. And it could all just wind up being a waste.

And yet it seemed like it might work. Basil ice cream is delicious. Pizza sauce is often sweetened with sugar. And tomatoes could easily play nicely with the tangy-ness of yogurt. So I tried it, and the results were surprisingly good. Rich with tomato, a hint of basil, and the tang of yogurt. Most of my colleagues (who are patient guinea pigs, but also not afraid to say what they don't like) liked it. One person didn't.

To make it, I started with a strawberry frozen yogurt recipe. I coarsely chopped two tomatoes and 8-10 basil leaves, and let those macerate with 1 cup of sugar for about 3 hours. The tomatoes released a lot of juice, so I cooked this down a bit until the juice thickened to the consistency of a light syrup (maybe 15-20 minutes?).

I then put the tomato mix into the blender with 1.5 cups plain full-fat yogurt, a little (1/4 tsp or so) salt, a few grinds of black pepper, and some lemon juice. After pureeing, the flavor was good but not very rich. I added a little bit of vanilla extract for richness and a couple pinches of citric acid powder to boost the lemon juice.

The result was rich (though I might cut the vanilla a bit next time) and tart at the same time, with the background of the basil. It was pretty interesting; kind of like a frozen and sweet gazpacho.
