Apparently they taste a little like pineapple. I found some white strawberries at the store a few months ago. They might have been the pineberries mentioned in the article, which are a cross between the white Chilean strawberries and another kind.

They're white with a pink tinge. They tasted kind of like how a strawberry smells, and a little like pineapple. A little sweet, not very acidic. Kind of like lychee.
