Does anyone know why we say we hull strawberries?

Cuz our mums did it in time immemorial? No, seriously, the second meaning of hull as a noun in the AHD is: "[t]he enlarged calyx of a fruit, such as a strawberry, that is usually green and easily detached": link). So, it went from a skin or husk which needs to be removed before the dining commences to the green, tough bit that needs to be removed before the dining commences. Works for me, but thanks I never heard of husking strawbs afore ...

Ceci n'est pas un seing.
