Bitter/Sweet

 The yummy, juicy summer treat known as watermelon wasn't always sweet, in fact it was bitter, small, with white meat, and thick skin. Seeds have been found in Libya from 5000 years ago and in Egypt in tombs from 3000 years ago, but they weren't valued for their sweetness they were precious both for their ability to rehydrate and their use in treating heat stroke by using the empty wet rind on the head. Watermelons slowly made there way around the globe and by the 17th century had reached the Americas. Farmers started selecting seeds from the melons with the most desirable characteristics the number one quality being taste. They succeeded by 200 AD at which time Hebrew tax records showed watermelon grouped with other sweet fruits and the paintings showed increasingly red meat in the watermelons and today we have watermelon nirvana.
