Ingredients

Scale

For the Blueberry Spread:

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

For the Sandwiches:

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
Extra lemon thyme leaves (optional, for garnish)

Instructions

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 to medium-low and simmer for 10 minutes. Lower heat to low and continue simmering for another 10 minutes, stirring often, 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. Evenly spread the blueberry lemon thyme jam onto each slice. Generously sprinkle shredded white cheddar and mozzarella cheeses over the jam. Top with the remaining 4 slices of bread to form sandwiches.
Grill the Sandwiches: Heat a 12-inch cast iron skillet over medium heat and melt 2 tablespoons of butter. Place two sandwiches in the skillet and cover with a lid. Cook for 2-3 minutes until the bottom is golden, then flip and cook for another 2-3 minutes until the bread is golden and the cheese is melted. Adjust heat to prevent burning. Transfer cooked sandwiches to a cutting board, add remaining 2 tablespoons of butter to the skillet, and repeat with the last two sandwiches.
Finish and Serve: Cut each sandwich in half. Sprinkle with flaky sea salt and garnish with extra lemon thyme leaves if desired for an aromatic finish. Serve warm for the best combination of crispy bread and melted cheese balanced by the sweet, tangy jam.

Notes

Use fresh blueberries for the best flavor in the jam.
Keep a close eye on the jam while simmering to avoid burning.
Adjust sugar to taste depending on the sweetness of berries.
A cast iron skillet helps achieve the desired crispiness.
Be generous with the butter to get a perfectly golden, crispy crust.
Flaky sea salt enhances the savory and sweet contrast in the sandwich.
This sandwich is best served immediately for optimal texture and flavor.
