In one sentence, describe what the following article is about:

“Hulling” basically means removing the core of the strawberry and the green leaves at the top. This is done instead of simply chopping the top of, because it allows you to remove the leaves at the top (which you surely don't want floating in your strawberry water) without wasting any of the delicious berry. The easiest way to do this is to use a regular drinking straw.  Position your straw at the bottom of the strawberry. Gently push the straw into the strawberry, so that it goes straight through the center. Continue pushing until the straw comes out the other side, with the core and leaves inside the straw. If you don't want to waste the strawberry cores or the drinking straw, you can just cut the leaves off your strawberries. After you’re sure all of the cores and leaves have been removed, put them into the empty pitcher. It’s best to use something with a wide brim, because you will be inserting a spoon to mash the strawberries. You can create this recipe in a drinking glass as well. If you want to make your strawberry water by the glass, simply halve or quarter this recipe. Using a wooden spoon or another utensil with a flat surface, muddle the strawberries. with a wooden spoon. Muddling means to smash the fruit in order to release their juices and intensify the flavor of your strawberry water. You don’t need to completely obliterate the berries, but make sure they’re all decently mashed to the bottom of your glass. If you’re trying to keep this recipe super health-conscious, you can skip this step and rely on the natural sugar of the berries. You can, however, add a bit of your own sugar to amp up the sweetness. Simply sprinkle or pour your sugar over the crushed berries, and then stir or mash it all together. If you’re not sure if you should add sugar, first try making this recipe without this step. Then, you can add sugar to the finished glass of strawberry water if you desire.

Summary:
Wash and hull your strawberries. Put the hulled strawberries in your pitcher. Crush the strawberries. Add sugar, if you want extra sweetness.
