You will need a lot of counter space for making these noodles, so make sure to clear the counters. Also make sure you use a lot of flour as you are working. We lay out rows of wax paper and flour that to lay the dough onto between settings.
Place eggs, water, flour and salt in mixer bowl. Attach bowl and flat beater. Turn Kitchen Aid stand mixer to Speed 2 and mix 30 seconds.
To test for perfect consistency: Pinch a small amount of dough together after mixing with the flat beater. If the dough stays together without sticking to your fingers, it should work well. It may be necessary to add a small amount of water or flour to reach correct dough consistency.
Exchange flat beater for dough hook. Turn to Speed 2 and knead for 2 minutes.
Remove dough from bowl and hand knead for 1-2 minutes. Wrap in plastic wrap and let it rest for 20 minutes.
Divide dough into 4 pieces before processing with Pasta Sheet Roller attachment.
Cut dough into pieces about 3/8" thick. Flatten each piece slightly. Set adjustment knob on Pasta Sheet Roller at 1. Turn mixer to speed 2 or 4. Feed flattened piece of dough into rollers to knead.
Fold in half and roll again. Repeat folding and kneading process several times, until dough is smooth and pliable and covers the width of the roller.
Lightly dust pasta with flour while rolling and cutting to aid in drying and separation. Knead and fold each piece of dough in the same manner.
Move adjustment knob to setting 2. Feed dough through rollers to further flatten. Do not fold dough on setting 2 or higher.
Change to setting 3 and feed dough through rollers again. Continue to increase roller setting until desired dough thickness is reached. Egg noodles are best at setting 4.
