Finally, cooking the sliced onions covered with a bit of water (and the flavorful fond left from searing the beef patties) and then uncovered with additions of ketchup, brown sugar, and Worcestershire sauce created a quick caramelized, sweet-savory onion jam that took these patty melts to the next level. Further, it protected the toast from getting soggy with beef juices. Transferring the seared patties directly to the cheese (American for creamy melting, Swiss for nutty flavor) jump-started the melting process. Pressing out thin beef patties a bit larger than the slices of toast made for quick-cooking burgers with loads of flavorful crust and a consistent amount of juicy beef in every bite. To get there, we started with lightly toasted bread, making it sturdier and less susceptible to getting soggy, ensuring that it crisped nicely in the pan. Turn cakes right side up and let cool for at least 20 minutes before serving.These patty melts boast juicy beef, jammy onions, perfectly melted cheese, and buttery griddled rye bread that's exquisitely crisp. Invert rack and tin carefully remove tin. Remove tin from oven and immediately invert wire rack on top of tin.

Bake until edges are well browned and tops are golden, about 14 minutes, rotating muffin tin halfway through baking.

Using rubber spatula, stir until combined, mashing any lumps against side of bowl until mixture is smooth. Whisk almond flour, sugar, all-purpose flour, and salt together in second bowl.

Immediately transfer butter to heatproof bowl. Cook, stirring and scraping skillet constantly with rubber spatula, until milk solids are dark golden brown and butter has nutty aroma, 1 to 3 minutes. Melt butter in 10-inch skillet over medium-high heat. Generously spray 24-cup mini-muffin tin with baking spray with flour. Adjust oven rack to middle position and heat oven to 375 degrees.
