Take the very young green shoots of the pumpkin plant. Wash them well and put them into a large saucepan, with a very little water seasoned with salt and a pinch of carbonate of soda; keep pressing them down into the water and boil till soft. Turn into a colander and squeeze very dry, put into a saucepan with one ounce of butter, pepper, salt, and a few drops of lemon juice. Stir about till thoroughly hot through, dish neatly, and serve.
