These are a dandy and delicious little side that pairs with just about anything.
oval shaped all-purpose potatoes: 6 large, 18 medium, 36 small (new)
3 tbs. butter
5 tbs. olive oil
Maldon or other sea salt
Heat the oven to 425°F (or 400°F for new potatoes).
Put each potato, in turn, in the bowl of a wooden spoon and cut 1/2″ slices to about 1/2″ from the bottom. Place a roasting dish over a medium heat and heat the butter and oil. Roll the potatoes around in the mixture, then arrange cut-side up and sprinkle with salt.
Roast as follows: large potatoes – 1 hour, 10 minutes, medium potatoes – 1 hour, small potatoes – 45 minutes.
