Sweeten your valentine's morning by topping his coffee with love. Spoon a bit of foamed milk on top, and use a squeeze bottle to draw a heart with room-temperature chocolate syrup -- store-bought or homemade -- just before serving. Make sure foam is dense and syrup is thin. Serve immediately; the image will last only a minute or two. This trick works on cappuccino and latte, or hot chocolate topped with whipped cream.
