This is a lesson in chaos. Try to enjoy it. It will be worth it, and even if after all your efforts you are left with nothing but a dusty kitchen, you can still avert tragedy with a box of dried spaghetti.
This is too much fun to exclude your children from, and you will be surprised when the result it not only edible, but wonderful. I did this with my son when he was only two. I put a sheet down on the floor of the family room and let him have at it. Against all odds my son provided us with dinner. I was amazed.
My hope is that some day I will be able to give my children some flour and eggs, walk away, and come back to the miracle of fresh pasta, but I think we're still a few years away from that.
There is a way to do this by hand, but I don't have the right rolling pin or even the space to do it that way, so I use a squeaky pasta machine that is at least forty years old. You can buy a used one on Amazon from $22. I think it's worth it. If you want to try it by hand, pick up a copy of The Classic Italian Cookbook by Marcella Hazan, another worthy investment.
One egg will make enough pasta for 3-4 people, two eggs for 5-6 people. We used about five eggs since we planned on making extra to freeze. It didn't look like much, but it was very filling.
Unfortunately, all this pasta was boiled to a mushy death by a helpful spouse. We ate it anyway and we'll do this again soon. Next time I make this I'll post pictures of the end result.
I love trying new foods, cooking, and gardening. I hope to share these experiences on this site. Thanks for taking a look!
