You've seen cherry tomatoes in salads. You've heard of pear (shaped) tomatoes if you make authentic Italian tomato sauces. Last year the grocery stores had tiny grape tomatoes for salads. This year, it's "strawberry tomatoes" from Dole. They come in sort of scarily symmetric vines that nestle into a long plastic clamshell box like eggs in an egg carton.
The back story is that they were bred in Holland, and are now grown in hothouses in Canada. Super sweet and meaty, they need to be kept on the counter, not in the refrigerator. Who knew?
You can get the seeds and grow them yourself. Or pick the Dole variety up at the Ballard Market.
