Cheese and Caramelized Onion Sandwiches

Directions

1. 1

   Step 1

   

   Peel the garlic and onion. Prepare two frying pans for cooking: it will be more convenient.

2. 2

   Step 2

   

   Cut the onion into thin half-rings. Heat half of the olive oil and half of the butter in a frying pan. Add the sliced onion and fry over medium heat for 5–7 minutes until golden, stirring occasionally.

3. 3

   Step 3

   

   Pour the balsamic vinegar and Jerusalem artichoke syrup over the onion. Add salt. Reduce the heat to a minimum and cook, stirring, for another 5–7 minutes. The onion will acquire a beautiful caramel color and become even softer. Remove the pan from the heat.

   TipIf the onion starts to burn, add 1–2 tbsp of hot water.

4. 4

   Step 4

   

   Spread one side of the bread slices with the remaining butter. Place the buttered side down on a clean, preheated frying pan and toast only that side for about 1–2 minutes until golden brown. Transfer the bread to a plate and rub the toasted side of each slice with garlic.

   Step 5

   

   Grate the mozzarella coarsely. Place the filling on the untoasted side of two slices: first a layer of grated mozzarella, then caramelized onion, and again a layer of mozzarella. Cover with the remaining bread slices, toasted side facing out.

6. 6

   Step 6

   

   Heat the remaining olive oil in any frying pan. Place the sandwiches. Fry over medium heat for 2–3 minutes on each side, pressing with a spatula, until the cheese melts and the bread becomes crispy.

   TipIf the cheese doesn't melt, cover the pan with a lid for 1 minute.

   Step 7

   

   Serve the sandwiches immediately after cooking, while the cheese is still stretchy.
