I really liked this flavor!  As someone with many food sensitivities who also avoids sugar, this is the perfect treat for me when I crave chocolate or baked goods.  The raw nuts are crisp and fresh tasting.  However, the price was very high for the quantity of product.  With less than 20 brazil nuts in the package, I felt a little gipped.  In future, I'll try making my own chocolate nut mix from bulk raw nuts, berries, and coco powder rather than spend $9 per package!  For that price, I'd like a lot more product.

I have been making Belgian waffles using the Stonewall Kitchen Farmhouse Pancake and Waffle Mix for over three years.  My waffles are undoubtedly the best ever!!!  I like my waffles light and crisp - I can't stand a heavy soggy waffle. These just melt in your mouth.  I have made homemade waffles, but I have yet to find anything that can compare to this mix.

We bought this to replace our Cafe Escapes Dark Chocolate Cocoa.  They are less expensive- but you get what you pay for.  This cocoa is watery brown sugar water with an aftertaste.  I do not recommend it.<a href="http://www.amazon.com/gp/product/B005K4Q1T0">Grove Square Hot Cocoa Cups, Dark,Single Serve Cup for Keurig K-Cup Brewers, 24-Count</a>
