Step-by-Step Instructions

Step 1: Prepare the Blueberry Lemon-Thyme Jam

1. In a 2-quart saucepan over medium-high heat, combine 1 pint blueberries, ¼ cup sugar, juice of 1 lemon, and the bundled lemon thyme.
2. Bring to a boil, then reduce heat to medium-low and simmer for 10 minutes.
3. Lower heat to low and simmer for another 10 minutes, stirring often, until thickened.
4. Remove and discard the lemon thyme bundle. Allow jam to cool for 10 minutes before using.

Step 2: Assemble the Sandwiches

1. Lay out 4 slices of sourdough bread.
2. Spread a generous layer of blueberry lemon-thyme jam onto each slice.
3. Sprinkle shredded white cheddar and mozzarella over the jam.
4. Top with the remaining 4 slices of bread to form sandwiches.

Step 3: Grill the Sandwiches

1. Heat a 12-inch cast iron skillet over medium heat. Melt 2 tablespoons butter in the pan.
2. Place two sandwiches in the skillet and cover with a lid.
3. Cook for 2–3 minutes until the bottom is golden brown. Flip and cook for another 2–3 minutes until the other side is golden and cheese is melted.
4. Adjust heat as necessary to avoid burning.
5. Repeat with remaining sandwiches, adding the remaining 2 tablespoons butter.

Step 4: Finish and Serve

1. Cut each sandwich in half.
2. Sprinkle with flaky sea salt and extra lemon thyme leaves for garnish, if desired.
3. Serve immediately for the best melty, crispy experience.
