In a medium bowl, whisk together 1/2 cup melted unsalted butter, 3/4 cup granulated sugar, 1 tablespoon fine-ground cornmeal, 1 teaspoon pure vanilla extract and 1/2 teaspoon kosher salt. Whisk in 3/4 cup honey, before whisking in 3 large eggs one at a time, only adding the next egg when the previous one has been fully incorporated. Once all the eggs have been added, whisk in 1/2 cup heavy cream and 2 teaspoons white vinegar until fully incorporated and the mixture has lightened.
