A stuffed 'Marrow' is very tasty. What you do is take a nice sized 'Marrow'(small enough to fit in the oven) and slice through the one end with a sharp knife, about 1.1/2 -2" opposite end to the stalk. You then scoop out the inside fleshy part of the Marrow and seeds, and stuff with semi-cooked vegetables, fish, prawns, meat or whatever takes your fancy, place the end that you sliced through at the beginning, back onto the end of the 'Marrow' then wrap the whole thing in foil(as you would with a 'Turkey')making sure the end cap is positioned and sealed with the foil, then place in the oven on a baking tray at a medium - high heat setting for approx. 1 and quarter hrs, checking and turning occasionally to ensure an all over bake.
