Lemon peel, along with other citrus skins, has been used for centuries in food and drink recipes. Originally from Asia, lemon has become important to European, Middle Eastern and Asian cuisines.^{[1]
X
Research source} There are dozens of lemon varieties, all of which can be preserved, though some varieties have oilier, and thus more fragrant, skin.^{[2]
X
Research source} Preserving lemon peel is a worth the effort, since fresh lemons are not in season year-round. Packed with vitamins A and C, potassium, fiber, polyphenol flavonoids that help lower LDL cholesterol, and calcium, preserved lemon peel can provide many nutritional benefits, particularly when eaten regularly.^{[3]

Method 1 of 4:

Preparing Your Lemons

1
Choose the freshest lemons you can find; hand pick, if possible. Some people are lucky enough to have lemon trees in their yards, or live next to someone who does.
- Sometimes lemon trees and shrubs have sharp spiky thorns, so wear protective clothing and gloves.^{[5]
  X
  Research source}
- If you have a very tall tree, use a lemon picker. Or, better yet, grab a friend and get two lemon pickers (or more).
2
Sort the lemons into two groups, and then wash and dry them. One group is those with only superficial blemishes on the skin and the second group is those with deeper bruises or blemishes.^{[6]
X
Research source}
- This is an important step if you have a large supply of hand-picked lemons.
- Separate them into two bags, or bowls. If you have help, have one person wash one group while you wash another, discarding any lemons that appear moldy or infected.
- Pat the lemons dry or let them air dry in an area with good air circulation, because they can start to rot if they sit in water too long.

Store whole, blemish-free lemons in a plastic bag in the refrigerator. If you are using the lemons right away, you can skip this step.
- Lemons last longer in a plastic bag in the refrigerator, nearly four times as long as being left out at room temperature.^{[7]

Cut around blemished sections of the lemons.^{[8]
X
Research source} The "cut into lemons" will need to be used first for your project, or stored in the refrigerator until you use them.^{[9]
X
Research source}
- Blemishes are not always terrible, but if you are going to be making something like jelly and or sugared lemon, you'd probably not want to eat an unsightly dark spot on a piece of lemon, so it's best to just dispose of them.
- If you want, juice the cut lemons right away. See Making and Freezing Lemon Juice, below.

Research source} A zester is a great tool for peeling only the exocarp (outside layer of the lemon's skin),^{[11]

Placing the portions in a glass mason jar, rather than a plastic bag, will ensure that the small portions are not crushed or crumbled in the freezer.^{[13]

Dry Preserving Lemon Peel

1
Using a potato peeler, cut off lemon peel in wide ribbons. Larger strips of peel work better for dry preserving.^{[15]
X
Research source}
- Use the remaining lemon fruit for juice. See Making and Freezing Lemon Juice, below.
- Save the pith for pectin by freezing in a plastic bag.^{[16]

  Research source}
2
Mix equal amounts kosher salt and sugar in a bowl. The volume of your mason jar minus the volume of your lemon peel is the approximate volume of salt/sugar mixture you will need.^{[17]
X
Research source}
- The volume will change depending on the size of mason jar you are using.
These are spices that will break down and diffuse into the sugar/salt/lemon mixture.^{[18]
X
Research source}
Repeat layers, to top.^{[19]
X
Research source}
Since you have only peel in this mixture, the sugar and salt work together to break down the skin and to preserve it, without making it overly salty or overly sweet.
6
Refrigerate up to one year. Preserving this way, the lemon peel should be able to keep for up to one year in the refrigerator.
- Note the date and label the mason jar.

1
Put on latex or non-latex gloves. Gloves will protect the citric acid in the lemon juice from going into small cuts and abrasions on your hands as you work with the lemons.
- Really, put on the gloves! You've heard the saying "Squeezing lemon juice on a paper cut"? That's exactly as painful as it sounds, plus the citric acid really does eat away at the skin.
Rolling the lemon on a cutting board with the palm of your hand starts to separate and break down the fiber in the lemon, making it easier to juice.^{[20]

Research source}
Most lemon juicers require that you slice the lemon in half in order to provide an open surface for the juice to escape.

Zest lemon skin with citrus zester.^{[21]
X
Research source} If you don't zest the lemons now, you'll end up wasting all that good zest! See Freezing Fresh Lemon Peel and Dry Preserving lemon Peel, above.
- You can either use a sharp potato peeler for large ribbons of zest for use in cocktails or to infuse olive oil or a citrus zester for smaller pieces of zest for use in cooking and baking.^{[22]

^{[23]
X
Research source} Depending on your preferred method of lemon squeezing, you may end up with pithy juice with seeds or fibers.
6
Filter lemon juice at least once. Straining the juice allows you to filter out the tiny seeds and other fibrous material so that the lemon juice is smooth and has no particles.^{[24]
X
Research source}
- Use either a double or triple layer of cheesecloth over a measuring cup, or a fine metal mesh strainer.
7
Save spent lemon piths in a plastic bag.
- These leftover fibrous parts are chock full of pectin, which is what makes jelly jelly-like, so use them instead of buying packaged pectin at the store for making jellies.^{[25]
  X
  Research source}
- Store pith in the freezer in a plastic bag or plastic storage container, if you are not making jelly or preserves now.^{[26]

Pour filtered lemon juice into ice cube trays, and freeze thoroughly. Freezing lemon juice allows you to preserve it for up to one year.^{[27]
X
Research source}
- For a useful lemonade variation, heat lemon juice and sugar (to taste) over a medium flame until sugar is dissolved. Let cool to room temperature and then pour into ice cube trays for easy lemonade ice cubes that won't dilute your lemonade.
Date the plastic bags and make sure to note whether the lemon juice is natural or has added sugar, and freeze for up to one year.

How do I sugar lemon shavings and keep them fresh to use as cupcake decorations?

Put the shavings in lemon juice and leave them in there for two minutes. Then, take them out and dip them in sugar. You can store the shavings in an air-tight container.
