One fruit, two fruit, old fruit, new fruit

KJ asks:

It's summer and I need some new food in my life.  What should I try?

Fresh fruit is one of my favorite summer treats.  If you are in the market for something new and exciting, here's some wilder things to try:

"Dragonfruit or Pitahaya" by Luke Lawreszuk is licensed under CC BY 2.0

Dragonfruit has the consistency of a kiwi but a milder, sweeter taste.  The outside is bright pink and green (looks like dragon skin) and the insides can be white or pink with black seeds.

Kumquats are about the size of grapes and look like small oranges.  Incredibly sour, you actually eat them whole, rind and all.  Rolling the rind in your hands before eating is supposed to release extra sweetness to balance out the tart, but personally I haven't had any luck with that.  Let me know if you do!

Rambutans, if you've never seen them before, may be one of the most alien-looking fruits out there.  Pink on the outside with a seemingly furry appearance, the pitted fruit inside is very sweet and refreshing.  Something to know about rambutans are not like bananas in that they do not continue to ripen after being picked.  When picking them, choose rambutans with a bright pink outside and the closer to green you can find the 'hairs', the better.
