Preheat the oven to 425 degrees F.

Place the sugar, salt, cinnamon, allspice, ginger and cloves in a bowl of a stand mixer fitted with a paddle and mix until combined. Add the eggs and continue mixing. Add the pumpkin and mix until combined. Gradually add the cream and evaporated milk.

Use a sharp paring knife to cut out the top of the acorn squash (you could also use mini-pumpkins). Use a melon baller to spoon out the contents of the squash. Remove some of the meat from the side of the squash so the sides are about 1/2-inch thick.

Fill each squash with the pumpkin mixture. Place the squash in a baking dish and add about 1-inch of water to the bottom of the pan. A water bath will protect the eggs from scrambling. Place in the oven for 15 minutes. Reduce the oven temperature to 350 degrees F and bake for another 40 to 50 minutes. Cool on a wire rack for about 2 hours.

Place the egg whites in a medium-size mixing bowl and whip with an electric mixer on medium speed until foamy. Increase the mixer speed to medium-high and gradually add the granulated sugar. Whip to stiff glossy peaks. Use a rubber spatula to fold in the powdered sugar. Place the meringue in a piping bag fitted with a star tip. Top each squash opening with the meringue. Place the meringue-topped squash under the broiler until lightly browned (you could also use a mini-torch to lightly brown the meringue). Serve and enjoy!
