Sift all-purpose flour, semolina flour, and a pinch of salt together in a large bowl. Make a mountain out of flour mixture on a clean surface; create a deep well in the center. Break eggs into the well and add olive oil. Whisk eggs very gently with a fork, gradually incorporating flour from the sides of the well. When mixture becomes too thick to mix with a fork, begin kneading with your hands.
Knead dough until it is smooth and supple, 8 to 12 minutes, Dust dough and work surface with semolina as needed to keep dough from becoming sticky. Wrap dough tightly in plastic wrap; allow it to rest at room temperature for 30 minutes.
Roll out dough with a pasta machine or a rolling pin to desired thickness. Cut into your favorite style of noodle or stuff with your favorite filling to make ravioli.
Bring a large pot of lightly salted water to a boil. Cook pasta in the boiling water until tender yet firm to the bite, 1 to 3 minutes (or longer depending on thickness). Drain immediately and toss with your favorite sauce.
