Perfectly Melting Cheese Slice - cooking recipe

Ingredients

SOLUTION
1/2 cup cold wheat beer (115 g or 115 mL) or 1/2 cup water (115 g or 115 mL)
14 g sodium citrate
CHEESES
3 cups sharp cheddar cheese, grated (200 g)
3 cups mozzarella cheese, grated (180 g)

Preparation

Preheat the oven to its lowest temperature.
Line a baking sheet with a silicone mat, or lightly oil the sheet, and place it in the oven to warm while you prepare the cheese.
SOLUTION:
Combine beer or water with sodium citrate in a pot. Stir until dissolved. Then bring to a simmer over medium heat.
CHEESES:
Add the grated cheeses gradually to the simmering liquid. Use an immersion blender to blend in each addition until it has melted and is completely smooth.
Pour the liquid cheese mixture onto the warm baking sheet. Tip the sheet as needed to form an even layer. Alternatively, pour the cheese into a mold coated with cooking spray. (A silicone tart mold would form 3 1/8-inch diameter circles).
Cover with plastic wrap, and refrigerate until fully set, at least 2 hours.
Cut into rounds or squares 7.5 cm or 3 inches across. Place plastic wrap or parchment paper between the slices to prevent them from sticking together, and store refrigerated or frozen.
