Crack the eggs into the bowl of a stand mixer. (If you're like me, then pluck out the pieces of shell.) Whip with a fork to break the yolks.
Add the oil, salt, then flour (and turmeric, if using) in stages until mixed.
Mix on medium for 6-10 minutes. Should be soft and a bit dry. If too dry add water a teaspoon at a time.
Take out of the bowl and put in a fairly large piece of plastic wrap. Wrap tightly and refrigerate for at least 30 minutes.
Remove from refrigerator and prepare as you see fit. Dough can be used for lasagna, fettucine, spaghetti. Plenty of choices online for how to roll out.
