I really like the frozen Corn Muffin Tops, but the mix resulted in a dryer product. I used the paper muffin liners and I think these might have added to the dryness.

Bottled like an energy drink, Switch, doesn't contain the things you'd find in other carbonated beverages. There's no sugar, no caffeine, no corn syrup, no preservatives or artificial colors.  Instead, what you get is a refreshing, all-natural, lightly carbonated tangerine-orange drink loaded with Vitamin C. Think of it as orange soda without all the things you don't want. Switch has just the right amount of carbonation to make the beverage refreshing without being filling.  It's a zippy beverage made with real tangerine, apple, and grape juices, and would make a refreshing beverage, lunch, dinner, or snack-time drink.  There was a slight aftertaste that I'm chalking up to either the can or the citrus, but it didn't get in the way of enjoying the drink.  Make the "switch" to Switch.

I remember the cool, modern Melitta drip coffee makers from decades ago. A visual delight of glass and wood (without a hint of plastic), they were elegantly ahead of their time. I wish I could say the same for their coffee. It's fine coffee. Good, actually. However, nothing really special. I would buy it again if priced right, but probably would not go out of my way to get it, and certainly not at a gourmet price point. I must be honest and say that with the Melitta name, I expected a little bit more. Maybe I just got a an "off" batch. Let's hope so.
