Preheat oven to 300℉. Like a baking sheet with parchment paper.
Whisk ¼ cup of sugar and the cornstarch together in a small bowl. Set aside.
Beat eggs in a bowl into soft peaks form. Then, gradually add in ¾ cup of sugar, continuing to beat until the sugar dissolves and stiff peaks form. Gently fold in cornstarch mixture and lemon juice.
Spread ¼ inch thick of the meringue in a circle on the baking sheet. Pipe or spoon the remaining meringue to form a taller edge around the circle to create a shallow bowl.
Bake in oven for 1 hour. Turn the oven off, don't open the oven, and leave in for 30 minutes.
Beat the powdered sugar and cream with an electric mixer until it's thick. Spread onto the meringue and top with fruit.
