I made cheddar biscuits with this and they came out a little dry the first time, but i adjusted the recipe and they were amazing. I just added a little more milk and another egg. (we have chickens that lay very small eggs, so 3 of our eggs is like 2 large store bought ones.)

I love, and use the empty containers for medicine/advil in my purse, desk, suitcase. Also line with felt to keep earrings. Perfect little size to disguise small valuables when traveling and LOVE the mints. Tiny and powerful without burning my mouth.

Ex Input:
I ordered Wolf Gang Puck's k cups, largely because of his reputation and my experiences at his restaurants, both of which are good. However, when I drank my first cup of the Breakfast Blend, I tasted no coffee...it was as if I was drinking hot water. I was very disappointed and will purchase only those k cups which I know to be good. Sorry Wolf Gang, this is a sleeper!
