To a small bowl, add the gelatin powder and water. Whisk until combined. Set aside for 5 minutes to thicken.
Step 2
Grate the mozzarella cheese and add it to a microwave-safe bowl. Transfer the bowl to the microwave, and heat the cheese for 20-30 seconds until all the cheese is melted. Whisk to ensure that solid pieces remain.
Step 3
Quickly add in the egg yolk, and whisk vigorously until the mixture is homogeneous. Microwave the gelatin in 10-second intervals until completely dissolved. Add it to the cheese and mix again. If the cheese has cooled ( making it hard to whisk), microwave it for 10 seconds before adding the gelatin.
Step 4
Place the cheese dough between 2 pieces of greased parchment paper. Press the dough to flatten it, then gently roll it out until 1/8 inch thick. Place the cheese dough sheet in the fridge for 30 minutes to set.
Step 5
Take the dough out of the fridge, and cut it using a pizza cutter. Slice it into ½ inch wide noodles. Divide the noodles into 2 portions.
Step 6
To serve, toss the noodles in warm water, drain, then transfer to a plate. Top it with your favorite sauce. Serve immediately.
