Sándwich de queso a la plancha con masa madre

Ingredientes

• 2 slices sourdough bread
• 1 tbsp unsalted butter
• 2 tsp mayonnaise
• 3.5 oz Cheddar cheese, freshly grated
• 1 oz Gruyère cheese, freshly grated

Preparación

1. 1

   Preheat a cast iron skillet over low heat. While the skillet heats, cut two 1/2-inch-thick slices of sourdough bread and freshly grate the Cheddar and Gruyère.

2. 2

   Spread 1 teaspoon of mayonnaise on one side of each slice of bread.

3. 3

   Add the unsalted butter to the skillet and swirl it around until melted.

4. 4

   Place one slice of bread mayonnaise-side down in the skillet. Sprinkle the grated Cheddar and Gruyère evenly over the bread, then place the second slice on top with the mayonnaise-side facing up.

5. 5

   Cover the skillet and cook over low heat for 2 to 3 minutes, or until the bottom slice is evenly golden brown and crisp.

6. 6

   Remove the lid and flip the sandwich with a spatula. Cover the skillet again and cook for another 2 minutes, or until the cheese is completely melted and the second side is golden brown.

7. 7

   Remove the sandwich from the heat and transfer it to a cutting board. Slice it in half with a serrated knife and serve immediately.
