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
Sandwiches
- 8 slices sourdough bread, each 1/4 inch thick
- 4 oz white cheddar, grated
- 4 oz whole mozzarella cheese, shredded
- 4 tbsp butter
- Flaky sea salt, for finishing
- 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 heat to medium-low and simmer for 10 minutes. Lower the heat to low and continue to simmer, stirring often, for another 10 minutes until the jam thickens. Remove and discard the lemon thyme bundle. Allow the jam to cool for 10 minutes before using.
- Assemble the Sandwiches: Lay out 4 slices of sourdough bread. Spread the blueberry lemon thyme jam evenly on each slice. Generously sprinkle shredded white cheddar and mozzarella cheese over the jam. Top with the remaining 4 slices of bread to form sandwiches, pressing gently to secure.
- Grill the Sandwiches: Heat a 12-inch cast iron skillet over medium heat and add 2 tablespoons of butter, allowing it to melt. Place two assembled sandwiches in the skillet, cover with a lid, and cook for 2-3 minutes until the bottoms are golden brown. Flip the sandwiches and cook for another 2-3 minutes until the other side is golden and the cheeses have melted. Adjust heat as necessary to prevent burning. Transfer cooked sandwiches to a cutting board, add the remaining 2 tablespoons of butter to the skillet, and repeat the grilling process with the remaining sandwiches.
- Finish and Serve: Cut each sandwich in half. Sprinkle with flaky sea salt and additional fresh lemon thyme leaves, if desired, to enhance aroma and flavor. Serve warm and enjoy the crispy, melty, sweet, and savory delight.
Notes
- The lemon thyme bundle should be tightly bundled to easily remove after cooking the jam.
- Use a cast iron skillet for even heat distribution and perfect toasting.
- Adjust sugar amount in the jam for your preferred sweetness level.
- Butter the skillet between batches to ensure a crispy golden crust on each sandwich.
- Serve immediately for best texture; sandwiches may become soggy if left too long.
