These are great beans for the price. If you live in a big city, however, I'd suggest buying green beans at a local Ethiopian shop or even a community Coop. I also remember a Pea berry out of East Timor that was outstanding, but this Tanzanian Pea berry is comparable to standard beans.

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.

I didn't expect much from powdered cocoa in a cup, but here's a tip: put on 8oz setting, then add a 1:1 ratio of heated milk. It tastes amazingly good!  Of course if you add a little Baileys Irish Cream, it tastes even better.
