Grapefruit comes from a subtropical citrus tree and is known for its sour to semi-sweet taste. Originally grown in Barbados and known as the forbidden fruit, grapefruit was later named because it grows in grape-like clusters. Grapefruit pairs well with hearty kale and creamy goat cheese, both of which work to tone down the sourness of the fruit. The salad is topped it with sherry vinaigrette, as it combines the complex acidity of wine vinegar with the sweetness of balsamic vinegar. Enjoy this great salad that is healthy, hearty and delicious!
