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.

I've tried all three new 'Dark' offerings from Gevalia and I think this is the best one from the three. Gevalia finally came up with coffee worth serving to your guests. Coffee has an earthy bold taste with little to none bitterness and no metallic after taste; it actually leaves a nice smooth tasty chocolaty after taste. The pack comes with 12 big T-discs that will brew 8 ounces of coffee. This coffee will delight those who love the darker roasts. Update: I am on my 5th cup of this coffee and it was really grown on me (changing from a 4 to 5 stars); it is quite tasty and smooth. This is one coffee that will truly satisfy the void that Sbux left. There will be some that will say that this is not the same as Sbux and it isn't! Try the coffee and give it a fair taste without trying to compare it to anything else you may find yourself quite surprised at the findings. Highly recommended and definitely will be buying this one again.

I have missed Bisquick since I became gluten free and am so happy to see they have gone gluten free. I've only made pancakes so far, but they are wonderful.
