I posted a few days ago about using my extruder. I finally figured out what I was doing and it works beautifully. After doing some research I realized I probably used a recipe that was too sticky for macaroni. I found several recipes online, all different. Long story short, practice with different recipes, the dryer the dough the better, but not crumbly type of dough. I had used a recipe with olive oil added and that's what made it so sticky. Even after kneading several times to add more flour it was still too sticky. I refrigerated for several hours and it extruded perfectly. My macaroni stuck together, but I think with some additional practice I will get this right. Love the spaghetti the extruder makes, so practice makes perfect!
