Old MacDonald's Potato Box Recipes 

Crisp Cottage Fries

Ingredients

4-5 medium potatoes (I like the red ones but any will do)
1 medium onion (optional)
enough vegetable oil to have about an 1" of oil in a large skillet
salt
pepper

Directions

Scrub and dry potatoes, peel onion. Using Mandolin slicer* or knife slice potatoes and onions crosswise as thin as you can. Heat oil hot. Carefully drop slices of potatoes and onion into oil. (I drop in one at a time, otherwise they tend to stick together.) Fry fast, separating potatoes and turning often until crisp and a golden brown. Remove cooked slices to allow more room in skillet until all are done. Drain well on brown paper or paper towels. Salt and pepper to taste. Serve with ketchup, if desired.
For less crisp potatoes, slice them a little bit thicker and don't cook as long.
