One bite and you’ll fall in love with these heart-shaped cookies.
Preheat oven to 250°F (120 °C). Line rimless baking sheet with parchment paper.
In large bowl, beat egg whites and vinegar until soft peaks form; beat in sugar, 2 tbsp (30 mL) at a time, until stiff glossy peaks form. Beat in cinnamon. To make free form hearts, drop about ¼ cup (50 mL) of batter onto baking sheet; with a knife or an off-set spatula, spread into the shape of a heart, approx 3-inches (7 cm) in diameter and 1-inch (2.5 cm) high. Bake for 1-½ hrs or until dry and crisp but not coloured. Turn off oven; leave meringues in oven for 1 hr longer.
In a large bowl, place chopped chocolate and Canadian Mascarpone cheese. In a microwave-safe bowl, heat 1 cup (250 mL) cream for 1-½ min on High (100%) power or until steaming. Pour over cheese mixture and let stand 2 min; gently whisk until well smooth. Chill completely in refrigerator, about 2 hrs. Whip chocolate mixture until light and fluffy. If mousse is too stiff or dry, add 1 tbsp (15 mL) cream at a time to smooth out to spreading consistency.
Spread mousse in shape of a heart on cookies, leaving a border to show off the white meringue. Cookies can be loosely covered and refrigerated for up to 8 hrs. Garnish with strawberries, if desired.
