Fruit & vegetableHarvest

A five-pointed oxalis fruit — pretty in a salad, and a documented problem if the kidneys are already in trouble.

Starfruit is a Southeast Asian oxalis-family fruit. Traditional use is as ripe acid fruit. Culinary amounts in a healthy adult are the path. People with significant kidney disease can have serious reactions to caramboxin and the oxalate load — this is not a ‘maybe.’ If kidneys are not well, pick another plate. Ripe yellow fruit is sweeter than green.

Flavor

Green-apple, oxalis sour, a little floral. Ripe yellow is milder. Green is a pickle.
