Deeply Rooted
That's good to know! Thanks!No, you need UNRIPE tomatoes for that. Ripe ones would bee too wet and mushy.
Also, you probably wouldn't want to try and make ketchup or tomato sauce. Heating tends to move the pigments towards the yellow/red part of the spectrum. That's why red tomatoes turn into red-orange tomato sauce. Whites turn yellow, yellows turn orange, red and pink, turn red-orange, purple and black turn deeper red orange......and green turn a really off-putting greenish brown.
Bear in mind though, that when I did the tests, I was using Green Zebras (which are actually a green with some yellow). These don't have any yellow pigment at all (which is why they still look unripe) so the color might be different (possibly a dark green, like pesto sauce or cooked spinach.)
