In a medium ovenproof glass bowl, combine 6 tablespoons unsalted butter, 3 tablespoons water, 1 tablespoon grapeseed oil, 1 tablespoon granulated sugar, and a pinch of kosher salt. And now, this is going to sound real weird so you're gonna have to trust me, but transfer the bowl of ingredients to the preheated oven and bake for 15 minutes, or until the mixture is boiling and the butter has started browning.
