01 - Mound flour on a clean work surface and create a well in the center. Crack eggs into the well with salt. Using a fork, gradually incorporate flour into eggs until a shaggy dough forms. Knead by hand for 8–10 minutes until smooth and elastic. Wrap in plastic and rest for 20 minutes.
02 - Combine mozzarella, ricotta, Parmesan, pepper, salt, and basil in a medium bowl. Mix thoroughly until all ingredients are evenly distributed and mixture holds together well.
03 - Divide rested dough into two equal portions. Roll each portion into thin sheets approximately 1/16 inch thick using a pasta machine or rolling pin, working from the widest setting to progressively thinner settings.
04 - Cut dough into 2-inch squares or rounds. Place 1 teaspoon filling in center of each piece. Fold dough over to create triangle or half-moon shape, pressing edges firmly to seal. Bring corners together and pinch to form traditional tortellini shape.
05 - Bring a large pot of salted water to a rolling boil. Gently add tortellini and cook for 3–4 minutes until they float to surface, indicating doneness. Remove carefully with slotted spoon.
06 - Heat olive oil in saucepan over medium heat. Sauté minced garlic until fragrant, about 1 minute. Add crushed tomatoes, sugar, salt, oregano, and pepper. Simmer for 10 minutes, stirring occasionally to prevent sticking.
07 - Gently toss cooked tortellini with warm tomato sauce until evenly coated. Plate immediately and garnish with fresh basil leaves and additional grated Parmesan cheese if desired.
