I cant resist giving you a quick background on Ewedu Leaf before I discuss its preservation.
Ewedu leaf ,for those who dont kow it ,is the local name for the Genus Corchorus .
Different common names are used in different contexts, with the name "jute" applying to the fibre produced from the plant, 'Mallow-Leaves" for the leaves used as a vegetable. On a lighter note, a friend's 3year old daughter asked for the English name of Ewedu and her mum put it up on facebook,asking for answers.
she did get many hilarious answers (you'd understand this better if you are from an ewedu eating background) well, I suggested the english name "we-do"!
Corchorus has a mucilagin…
