We love Melitta coffee pods.  Makes a perfect cup of coffee every time. The coffee is always delicious, even the decaf blend!  If you have a coffee pod machine, try all of their blends...they're great!

Stonewall Kitchen Farmhouse Pancake and Waffle Mix is definitely a mouthful in name but, in taste, not so much.  Don't get me wrong, it's not bad but, you could find any number of "mixes" that taste just as well and some even better.  I know my taste buds aren't the same as yours so, what's just decent to me may be great to you.  I also wish I had bought just one can instead of 2 huge 33 ounce cans.  I finished the first can, I'll give the other can away and, I'll continue trying other mixes until I find the "best mix" out there.  So far I seem to only be satisfied with a homemade mix for my waffles.  My preference is for waffles over pancakes but, this didn't make it on either count.  I even tried adding things to it but it didn't really help.  Maybe it's just me.  Try it if you like but remember, buy only one can just in case you're like me.  You can always buy more.

My favorite blend of my favorite coffee.  Used to have to smuggle a few pounds of the stuff back in my suitcase everytime I went out to the midwest! Now I can get in k-cups.  Yay! Good price on amazon, but super saver shipping takes forever! Fedexing it to the post office makes no sense.  just fedex it to me and shave 2 days off the wait already!
