For the first time, Grandpère grew heirloom tomatoes in his garden. The tomatoes don't look beautiful in the pictures, nor are the colors true, but the taste is delicious. The excellent flavor is different from any tomato I've eaten. Wikipedia says:
Heirloom tomatoes lack a genetic mutation that gives tomatoes an appealing uniform red color while sacrificing the fruit's sweet taste.
The fruit in the pictures are not quite ripe, because GP is competing with a bird to pick the tomatoes whole without chunks pecked out of them. The tops of the tomatoes never turn red, so the time is ripe for eating when the feel is slightly soft to the touch. I'm told by a friend that when the tomatoes can be found in stores or markets, they are expensive. What a treat for me.
