Plot Summary:Mary makes a star out of one of her all-time favourite ingredients and whips up a Lemon Raspberry Loaf with a bright pink glaze; Lemon Parmesan Chicken that is fancy enough for guests but quick enough for any night of the week; a zesty take on carbonara - Creamy Lemon Crab Pasta with a nutty sesame topping; and to finish it all off, a lemonade that is infused with seasonal berries and fresh mint.
