Ingredients

Scale

Blueberry Lemon Thyme Jam

  • 1 pint fresh blueberries
  • 1/4 cup white sugar
  • Juice of 1 lemon
  • 1 small bundle lemon thyme, bundled with kitchen twine

Sandwich

  • 8 slices sourdough bread, each 1/4 inch thick
  • 4 oz white cheddar cheese, grated
  • 4 oz whole mozzarella cheese, shredded
  • 4 tbsp butter
  • Flaky sea salt, for finishing

Instructions

  1. Prepare the Blueberry Lemon Thyme Jam: Combine the fresh blueberries, white sugar, lemon juice, and bundled lemon thyme in a 2-quart saucepan over medium-high heat. Bring the mixture to a boil, then reduce the heat to medium-low and simmer for about 10 minutes. Lower the heat to low and simmer for another 10 minutes, stirring often, until the jam is thickened. Remove and discard the lemon thyme bundle. Allow the jam to cool for 10 minutes before using.
  2. Assemble the Sandwiches: Lay out 4 slices of sourdough bread. Spread the cooled blueberry lemon thyme jam evenly onto each slice. Sprinkle the white cheddar and mozzarella cheeses generously over the jam. Top with the remaining 4 slices of bread to form sandwiches, pressing lightly to secure.
  3. Grill the Sandwiches: Heat a 12-inch cast iron skillet over medium heat and add 2 tablespoons of butter, letting it melt. Place two assembled sandwiches in the skillet and cover with a lid. Cook for 2-3 minutes until the bottom is golden brown, then carefully flip the sandwiches, cooking for another 2-3 minutes or until the other side is golden and the cheese is melted. Adjust the heat as needed to prevent burning. Transfer the cooked sandwiches to a cutting board, add the remaining 2 tablespoons of butter to the skillet, and repeat the process with the remaining two sandwiches.
  4. Finish and Serve: Cut each sandwich in half. Sprinkle flaky sea salt and extra lemon thyme leaves over the sandwiches for a fragrant and flavorful finish. Serve immediately for the best texture and taste.

Notes

  • Use fresh blueberries for the best flavor in the jam.
  • Be generous with the jam to achieve a nice balance of sweet and tangy flavors in the sandwich.
  • Adjust butter quantity as needed for crispiness and browning but avoid excess for a lighter sandwich.
  • Covering the skillet helps the cheese melt evenly inside the sandwiches.
  • Flaky sea salt adds a nice finishing touch but can be omitted for a lower sodium option.
  • Use a cast iron skillet or heavy-bottomed pan for optimal crust formation and even cooking.
