The hot summer weather can leave you parched and worn out. A cool way to revitalize is by adding a drop of lemon juice to your ice cube trays. It doesn't matter what you plan on adding ice to (water, soda or even tea) because almost everything tastes better with lemon. Halve a fresh lemon, then squeeze it into the water when you refill your ice cube trays. A few hours later, you'll have the perfect addition to any cool drink.
If you really want to kick up the flavor a notch, skip the water entirely and just freeze the lemon juice in your trays. The result will be tart, tangy and a great complement to just about any iced beverage.
