"Lemon juice is the strongest food acid in our kitchens, strong enough to make life unbearable for most bacteria," says Robert Wolke, professor emeritus of chemistry at the University of Pittsburgh and the author of What Einstein Told His Cook 2: The Sequel, Further Adventures in Kitchen Science (W. W. Norton, $26).
Use Lemon to :
1. Sanitize a chopping block. Run a slice of lemon over the surface to disinfect.
2. Eliminate the browning that occurs when food sits out too long.
Sprinkle apple or pear slices with lemon juice before serving,
or squeeze a bit into guacamole and give it a stir.
3. Remove tough food stains from plastic and light-colored wooden cutting boards.
Slice a lemon in half, squeeze the juice onto the soiled surface, rub,
and let sit for 20 minutes. Rinse with water.
4. Fade tea stains on cloth. Dilute lemon juice with an equal amount of water.
Use an eyedropper or a Q-tip to make sure the juice targets the stain.
Thoroughly flush with cool water.
5. Decorate on the cheap. Fill a glass bowl with lemons for a sunny centerpiece.
Or display a row of them along a windowsill.
6. Relieve a sore throat. Cut a lemon in half.
Skewer one half over a medium flame on a gas stove or an electric burner set on high
and roast until the peel turns golden brown. Let cool slightly, then mix the juice
with 1 teaspoon of honey. Swallow the mixture.
7. Whiten fingernails. Rub a wedge on the surface of your nails.
8. Shine the interior of copper cookware. Sprinkle a lemon wedge with salt, then scrub.
9. Brighten laundry whites. Add 1/2 cup lemon juice to the wash cycle of a normal-size load.
10. Remove soft cheese or other sticky foods from a grater.
Rub both sides of the grater with the pulp side of a cut lemon.
