If you have a food processor, you can use it, fitted with the metal blade, to make pasta dough. This will save time and effort at the mixing stage, but it is still very important to knead the dough by hand after mixing. Overloading the machine will prevent it from mixing evenly - use a maximum of 450 g flour for any one batch.
Put 300 g sifted strong plain white flour and 1 tbsp salt into the food processor bowl. Add 1 tbsp olive oil and 1 egg. Work until the egg is incorporated.
With the motor running, add two more eggs, one at a time through the funnel, and work until a dough begins to form.
Turn the dough out, then knead the dough until it is smooth and elastic (see step 5). Cover and let rest for up to 1 hour before rolling and cutting.
