Citrus is a perfect example. We've all had water with lemon or lime added and I personally find it to be a lovely combination. You may also want to try orange, grapefruit, and tangerine. Just slice a segment, squeeze it into your glass, and drop the whole thing in. Don't forget to wash off the rind if it's going into your water.
One of my favorite accessories for water is dill weed. It's bright, fresh, and slightly sweet flavor goes nicely with water. I especially love this combination during hot weather.
Another hot weather addition I enjoy is cucumber. Add a few thin slices to your glass with some ice cubes and give it all a gentle stir before you fill it with water. Delish. And if you're going for a spa-like indulgence, cucumber and dill are great together in water.
Minted water is a lovely treat. You may need to muddle the leaves or crush them with your fingers in order to get them to release their minty goodness into your water, but it's worth the effort and extraordinarily refreshing.
When berries are in season, they too make great water accessories. Slice up a strawberry or muddle a couple blueberries into the bottom of your glass and you're in for a treat.
Many varieties of melon are also wonderful in water. Add a small amount, like a melon-baller's worth, and muddle it with your ice. Yum!
There are lots of options available to add some razzle-dazzle to your water. Most of them are cheap and easy to get your hands on and you need only use a tiny amount to dress up your water. Remember, we're going for water with a hint of lemon, not lemonade.
Get creative and think outside the box. If you find other things to add to your water, I'd love to hear about them.
Viva la agua!
