I took some miracle fruit berries to work, and we all played around with them. In spite of sucking the berries very hard, and chewing them up and swishing them around in our mouths, two people had very little sweetness response, and still thought the lemon juice and vinegar tasted very sour. Others were chugging the lemon juice like crazy, and the rest of us were sort of in the middle.
I am wondering if there is something to the genetic makeup of people, where it works or it doesn't, sort of like being able to taste PTC or not...Carolyn
There may be some berries that don't have enough ripe flesh to make much of an impression. I'd give those people two or three fruits to insure they've been adequately dosed.
There also may be varying degrees of response in people, depending on how accustomed they are to eating sweet things. This is just speculation on my part.
I enjoy the fruits with mediocre citrus, but otherwise don't find myself drawn to them.
