3- Fill a large bowl with cool water
Soak your lettuce in a large amount of cold water. Move the water around by swirling the water vigorously. If you got the lettuce from a farmer’s market, it will probably be more dirty than from the store.
If you are going to dry the lettuce with a spinner, wash the leaves in the bowl and colander that came with your spinner.
4- Inspect whole heads
If you are washing whole heads of lettuce, make sure to thoroughly inspect them. Gently open the heads and check between the leaves for dirt. Gently bend the leaves back and away from the core to allow water to get between the leaves. Make sure to check the area where the leaves are attached to the stem.
You can leave the lettuce heads together for grilling
5- Let the dirt fall to the bottom of the bowl
Walk away from the leaves and let the dirt settle to the bottom of the bowl. After about 10 minutes, take the greens out of the water. Make sure not to go near the dirt at the bottom of the bowl. Gently shake the excess water off of the leaves and lay them on a paper towel.
