This is such a popular dish that its Italian name almost does not need translation. A common mistake in making this is not sautéing the vegetables enough. Do not be afraid of overcooking them here. Whatever dubious virtue there may be in undercooking vegetables, it certainly does not apply to pasta sauces. By cutting the vegetables in tiny pieces and sautéing them thoroughly, you will concentrate their flavor and infuse the cream with it. Done properly, this is a heavenly dish with the rich, sweet flavors of spring.
