Our friend Ronette gave us some from her garden. Tamarillos, or tree tomatos, are gorgeous looking fruits, but don't let the good looks deceive you, they are terribly sour and bitter, best eaten stewed. Which is what I'm doing right now.
The first time we came across these were when we holidayed on the Cook Islands, before we moved to NZ. We bought six, washed them, and put then in a fruit bowel in our room. I couldn't help myself and bit into one, and it was so sour I shrunk 6 inches instantly. Not believing that was the way the fruit was supposed to taste, I picked up another one immediately. The rest went into the garbage.
A few years ago, I bought a bunch and made chutney with onion, chili and raisins. As usual, I didn't consult any recipes, but mysteriously I got spectacular results, but I've never been able to replicate it. I might give it another try this year.
