Personally I am approaching harvest time for my favourite survival food. You have to stake out a territory early from other scavengers and gathering tools consist of a large sack ( often easily procured on site) and a long stick with a hook ( good practise with your PSK gaff hook.) The peak day is on December 26. Look for square, rectangular and sometimes round subspecies with an overall glossy brown colour and various colourations of pineapple yellow, cherry red and other regional variations. Preservation is by simple freezing or submersion in alcohol, usually brandy or rum ( preferred.) Since alcohol is the purest form of vegetable matter this is easily shared with vegetarians. Vegans make take issue with the milk and egg unless procured from free range sources.
