velonomad's pie post motivated me to submit my desert version of summer pickings:
This 4 meter high prickly pear in my front yard yields hundreds of pounds of fruit every summer and provides me with enough sweet juice to last well into winter. I remove the numerous seeds with a juice extractor and freeze the decanted juice in small plastic containers. The frozen juice is added to milk, water or soy milk with yogurt or protein powder and blended. It makes a great recovery drink and prickly pear has purported antioxidant properties. The picking and fruit cleaning is a bit prickly - but worth the discomfort.
