This deliciously unique ice-cream dessert has ricotta cheese as its star ingredient. A fantastically soothing detour from regular ice cream, when pureed the ricotta lends a rich creaminess without imparting a cheese flavor. This soft cheese is a good source of calcium and protein. Ricotta also contains selenium, an antioxidant that can help prevent arthritis, and is surprisingly lower in fat content than cottage cheese. The lemon zest adds a subtle summertime freshness. When served with fresh organic blueberries, this dessert is perfect for your red, white, and blue Fourth of July celebration!
