First, Mill your grains into a semi fine flour. I always mill about 100g extra for dusting my counter and pasta after rolling.
Add your flour to the stand mixer fitted with the roller attachment (Ankarsrum) or paddle/dough hook (KitchenAid)
If you are hand kneading, add your flour to a clean surface and make a well in the center.
To your flour, add your eggs and oil. I use Olive oil or avocado oil.
You want to knead dough until it has a glossy sheen to it. In my Ankarsrum mixer, it takes about 8 minutes. I also lock my roller arm about an inch from the side of the bowl as it helps it knead better!
Once the dough has kneaded, you want to wrap with plastic wrap and place in the fridge for about 30 minutes. This is a crucial step or your dough will not roll out. It will shrink back up everytime you attempt to roll. (Trust me, I tried to rush it once)
After the resting period, I divide my dough into about 8-10 smaller pieces and begin rolling them out slightly to run through my pasta sheeter.
Depending on what type of pasta you are making, you will roll and shape differently.
In my Ankarsrum sheeter, I run it though once on a "2" first and then run through again on a "4".
