Sweet Potatoes

I decided to have green apples and prunes added with sprinkle of sweet sour plum powder as lunch.
But as I was walking around the supermarket, I saw little sweet potatoes with purple skin.
Thus I decided to get them too.
Below is the mixture of 2 small green apples, 3 prunes, 2 sweet potatoes and a dash of sweet sour plum powder.
(picture don’t look appetizing.. I know :p)

I did not know I got 2 different color flesh potato.
1 is yellow another is purple.
To me, purple skin potato are the sweetest with yellow flesh.
They taste so good!
Purple flesh also taste sweet. They cooked pretty fast .
But I prefer the yellow flesh.

The green apples are too sour! :/
