My honey has a serious sweet tooth, which I accommodate by preparing him a weekly dessert. Martha White's Muffin Mix is very convenient to prepare because it only requires one-half cup of milk, which I toss into my cuisinart; and wah-la six beautiful muffins with virtually no prep time. They are moist, delicious, and economic.

Ex Input:
This was the most potent orange drink I have ever had. It might be "100% juice," but this drink has some kick.  There are no artificial sweeteners in this drink, but it is so highly concentrated that it was overwhelmingly sweet and even the tang of the carbonation couldn't cute into the sugary flavor.  It was WAY too strong for me and I thought it had kind of an odd aftertaste, but if you like carbonation and have a powerful craving for orange-tangerine, this is the drink for you.
