MMM..on the subject of potatoes fried in grease: when I was a kid, my dad would make fried potatoes. Here's the general recipe:
take one big glob of saved bacon grease, fry onions and cooked (boiled) potatoes in. When they are almost done, tear up some white bread and press it into the excess grease to soak it up and fry the bread. Serve! It tasted sooo good! (though now, eating that much fat at once would make me sick to my stomach.
When I became vegetarian, dad changed the bacon grease to crisco or some other solid veggie fat.
I recently heard a suggestion to use daikon radish instead of potatoes for hash browns and fries (I bake my "fries"). I picked some up and intend to try it sometime this week.
