I used the small cup setting and even opened up the cap and scraped the excess mix out of the cup and it is still very weak tasting.

Ex Input:
I would not order these K-cups again.  Maybe I'm spoiled with Godiva hot chocolate, but I think Swiss Miss hot chocolate has more chocolately flavor than these K-cups and I wouldn't waste my money on these.  It comes out a pinkish color that is not appetizing at all.

Ex Input:
A friend's favorite candy is "After Eight", but they are not available anywhere in my area.  I couldn't find them on-line either.  Amazon.com came through.  These are imported from England and the most delicious peppermint.  These are so thin with a smooth mint cream center and a dark chocolate shell.  If you just want a little taste of mint, this is for you.  Really special with a cup of hot coffee!
