645. Vegetable Marrow.—Choose eight young small ones, with smooth skin, and put them to boil in two quarts of water, in which you have put one ounce of salt, the same of butter, try with a needle if tender, then dish them tastefully on mashed potatoes in a dish, put half a pint of melted butter in a pan when near boiling, add a liaison of a yolk of an egg, two pats of butter, a little sugar, the juice of half a lemon, sauce over and serve; if they are rather large, cut them in two length-wise; if in smaller pieces, take all the inside out and boil till tender, and warm in the above sauce. You can also make a nice demi-glaze, as No. 132, and let them simmer in it for twenty minutes; do not break them, as they would then be unsightly; they can be made into soup like cauliflower (No. 207).
