To make 12 cups of juice, use 36 oranges. A sacred word. Really good hash made in a heavy skillet from cold roast and cooked potatoes is food worthy of the gods. Work on it. The secrets are in the skillet, preferably cast iron, and your patience to let the food brown in the skillet.
Omelets are also easier with the right pan.
Omelets are good for exhibitionist tendencies, because the cook is on display while standing there making the omelets. For a brunch, make larger ones in a big non-stick pan, and divide them onto hot plates to serve. Or get two small skillets going and make them to order. The host who wants to relax should plan something else, obviously. Toast a few slivered almonds or other nuts until fragrant to sprinkle over fruit salad or ambrosia, into green salads or to garnish a curl of whipped cream atop a dessert.
