This was my first time experimenting with freeze-dried beef liver, and I would say it was a great success. I found it at my local pet store labeled as “PureBites Freeze Dried Beef Liver Dog Treats.” If you’re unsure about what you’re getting, just check the label on the package. The only ingredient listed should be “liver,” with no additives or preservatives.
The freeze-drying process preserves the flavor and nutritional value of raw beef liver. It also preserves the odor. Our dogs were going crazy over the liver-y aroma wafting through the kitchen as I was preparing these treats, but I personally found the odor, to be blunt, disgusting. It was very stinky business grinding the freeze-dried liver pieces into powder (and I immediately washed out my food processor extremely well afterwards). But I’ve decided that my momentary revulsion was worth it, because all the dogs LOVED these treats. Each dog very enthusiastically gobbled up a treat as soon as they were cool, and even my pickiest taste-tester begged for seconds.
The tomato paste turns this dough a reddish color, so I decided to cut the treats out using a heart-shaped cookie cutter appropriate for the season. Wrapped up in pretty packaging, these biscuits would make great valentines for your furry friends.
