Kale: Kale is a cruiser’s best friend. A leafy green vegetable that can last 2-3 weeks fresh. It can be kept out, refrigerated, or even frozen without losing its texture. Wrap stems in damp paper towel and store in plastic bag. This miracle veggie is packed with nutrients and is easy to steam. Just be sure to steam long enough, or it can have a peppery flavor.
Kohlrabi: Kohlrabi is crunchy and slightly sweet vegetable that can be used in various ways. Cut the leaves off and steam like kale. Store the bulbs in a perforated plastic bag or wrapped in damp paper in cool dark area. The bulbs can be steamed, or eaten in stir-fries. Lasts 2-3 months refrigerated.
Leeks: Delicious in quiche or stir-fry, leeks are not the most cruiser-friendly of all the onions. They should be refrigerated in perforated plastic. If you do not have refrigeration store in a damp paper towel in a cool part of the boat. Stored under proper conditions leeks can last up to 2 months.
Lemons: Lemons and lemon juice are great for cooking or just squeezing one into a glass can improve or at least mask the taste of occasionally questionably tank-flavored water. Store in fruit hammock out of the sun. In a cool environment lemons can last up to 6-months. Do not refrigerate until they are cut.
Lentils: Dried lentils are a great source for protein and do not have to be soaked before cooking like many dried beans and legumes. Though lentils have a bad reputation for being bland and boring, with the proper spices and seasonings lentils can be delicious. They are a staple in Indian dishes. See Beans.
Lettuce (Romaine): A shore luxury, even under the best of circumstances lettuce only can last a little over a week. Buy with roots if possible and keep bottom inch submerged in water. If storing in water is not possible place in a perforated plastic bag in refrigerator.
Limes: Limes are historic sailing food for preventing scurvy. Squeezing a little in water from the tanks can improve the taste immeasurably, but perhaps most important, lime juice can kill harmful organisms in unpurified drinking water. So if you are in Mexico or another area with questionable drinking water be sure to squeeze a little lime juice in your drinks. Store in fruit hammock out of the sun. After you cut one, store in the refrigerator. If cruising in a cool environment limes can last several months.
Longan Fruit: This tasty light-tasting fruit is common in Southeast Asian markets. Simply peel off the brown exterior to revel delicious white flesh surrounding a stone. Similar to a lychee but slightly smaller and tarter peeling and eating these fruits can get addictive. Definitely pick some up if you see them at the market. Refrigerate or store in a cool moist place. Stored properly they can last 2-4 weeks refrigerated.
Lunch Meat: A cruising go-to. Easy for on-the-fly sandwiches and quick throw-together meals. Must be refrigerated.
Lychee/Litchi: Lychees are ubiquitous in Asia and relatively easy to find around the world. Walnut-sized, a puckered pink exterior protects the translucent white fruit which surrounds a small black seed. With a unique sweet flavor this fruit is both easy and fun to peel and eat. Refrigerated or stored in a cool damp environment lychees can last 3-5 weeks refrigerated.
