This recipe I only made twice but came out perfectly both times (before I dried out the dough the second time). Even though I am not a huge fan of spinach pasta, my dad is. He really appreciated how delicious it was. The recipe is by Paula on Bell'alimento.
Ingredients:
2 3/4 cups all-purpose flour
3 eggs
pinch salt
1 cup cooked spinach - pureed
Procedure:
Sautee spinach in a pan with a tablespoon of olive oil and a clove of garlic until reduced by half.
Immediately transfer to ice water then puree it using a food processor.
Place flour into the bowl of your stand mixer. Create a well.
Add eggs, salt. Using paddle attachment, mix together until well combined. Add spinach.
Continue mixing until a ball forms. Scrape sides as necessary. Adjust if necessary. Add more flour if dough is too wet.
Switch to dough hook and knead dough for approximately 5-6 minutes.
Cover mixing bowl with kitchen towel and allow dough to rest for at least 30 minutes.
Attach roller attachment to mixer. Cut dough ball into 4 equal portions.
Take 1 portion and flatten it with your hand. Run through roller attachment until it reaches a level 4 thinness.
Attach Fettuccine attachment to mixer. Feed dough through.
Lay fettuccine on a lightly floured work surface.
Continue same process with 3 remaining dough portions.
