If you like the sweet & tart contrast of Sour Patch Kids and Lemon Heads, try nature’s version: Kumquats.

You can pop the olive-sized fruits right into your mouth like candy. No peeling necessary: In fact, the peel has a sweet taste that mellows out the sourness of the fruit’s flesh, for a balanced burst of fresh citrus flavor.
I recently found them at Whole Foods Market for $4.99/lb, which means that a dollar’s worth is guaranteed to be enough to satisfy your candy craving. The Kumquat growing season (November to March) is ending soon, so try them while you can!
For more of a challenge, search the internet to find plenty of recipes for cocktails, chutneys, or fruit salads featuring kumquats.
