Now, the answer to our Geo Quiz. We were looking for the name of an African tree known for its highly-nutritious fruit.

The answer is the baobab tree.

Across Africa, the fruit of the baobab tree can be as large as a melon or as small as a light bulb. The ones you find in Malawi are somewhere in the middle.

“It's a greenish velvety fruit which is about the size of a child's head, a baby's head.”

That's Chris Dohse, who works with baobab farmers in Malawi. If you didn't quite catch what he said -- that's thanks to a particularly bad phone line from Malawi.

He said the greenish velvety fruit of the baobab is about the size of a baby's head. Dohse also says the flavor of the fruit's pulpy, fibrous interior is hard to describe.

“It's difficult to compare it with other fruits, because it has a very sourish taste. But it is not at all comparable to something like a banana or an organge or any other fruit I have eaten so far. It's a pretty unique taste.”

I'll jump right in this time.

He says it's difficult to compare the baobab fruit with other fruits. It doesn't taste like a banana or an orange or any other fruit he's eaten so far.

But he does say it tastes "sourish."
