Trying Out Some Minneola Tangelos

I saw these at Cold Storage the other day. That protruding bell shape reminded me of a Japanese dekopon, so I picked up a couple of them in the hopes that they might taste similar too. Unfortunately the first one was sour...extremely sour. It was so sour that my face just clenched up when eating it. But the second one was extremely sweet, as if it were injected with sugar water or something. They were both seedless either way.
