TIP: When you get your berries home, prepare a mixture of one part vinegar (white or apple cider) and ten parts water. Dump the berries into the mixture and swirl around. Drain, rinse if you want (though the mixture is so diluted you can't taste the vinegar,) and pop in the fridge. The vinegar kills any mold spores and other bacteria on the surface. Raspberries will last a week or more, and strawberries go almost two weeks without getting moldy and soft.
Cleaning fruit - fill sink with water, add 1 C. vinegar, mix. Add all fruit/veggies and soak for 10 minutes. Water will be dirty and fruit will sparkle with no wax or dirty film. Great for Berries too--keeps them from molding.
Those packages of pre-sliced apples you can buy at store are great for a healthy snack on the go but the price can add up. Make your own by slicing apples, soak in cold water for 3-5 minutes, then soak in a lemon-lime carbonated soda (such as 7-up or sprite) for 3-5 minutes. Divide into snack size portions and store in Ziploc bags in the fridge. The lemon-lime soda will keep the apples from browning and make them last. Will have to try
