Labeling Preserved Food

Why label preserved food?

Without a label, you cannot tell the green beans from the dilly beans, or this year's batch from last year's. A label also lets you use older food first and keeps everyone in the household on the same page. If a recipe source is later found to be outdated, the label tells you which jars are affected.

Labels matter more when food is shared or given away, since the person receiving it needs to know what it is. Labeling is also a courtesy to the next person who opens your freezer. A guest, a family member or a neighbor helping out should be able to read what is there without asking. Clear labels make it easier for others to help with cooking and cleanup, and they help in an emergency when you are not around.

What information should a label include?

At minimum, write the name of the food, the date it was preserved and the method, such as frozen, canned or dried. A batch number helps if you made several in a day. For canned foods, many people add the recipe source so they can check it later.

For anything you give away, add the ingredients, especially anything that could cause an allergic reaction, and a note on storage, such as keep refrigerated. Decide on a format once, such as food name, then month and year, and write it the same way every time so you can read a shelf of jars at a glance. Share the system with everyone who helps. A shared system prevents confusion and means a helper can put things away correctly without asking.

• Name of the food
• Date preserved and method
• Batch number or recipe source
• Ingredients and storage note for gifts

What materials last?

Use a permanent marker or a waterproof pen. Paper labels can come loose in damp conditions or in the freezer, so use freezer-safe labels or write directly on freezer bags. For jars, a label that sticks and peels off cleanly makes reuse easier.

Test your marker on a spare label and wipe it with a damp cloth to see if it smears. If you freeze liquids, leave a patch of the container dry and label it before filling. Condensation and frost make it hard to write on a cold surface later. Peel-and-stick labels work best on dry, room-temperature surfaces, so apply them first.

Where should labels go?

Put the label where you can see it when the food is on the shelf or in the freezer. On jars, the lid is a common place for the date and a side label for the name. On bags, write on the flat part before filling, so you do not struggle with a full bag.

Avoid writing only on the lid of a canning jar if you store jars without lids on, or if lids may be swapped. If you reuse jars, remove old labels completely, since a half-peeled label with the wrong date is worse than none. Soaking in warm soapy water usually loosens adhesive, and a little cooking oil can help with stubborn residue before washing again.

How do labels help with rotation?

Labels make first in, first out possible. When you can read the date, you can pull out the oldest first. A quick scan each month shows which items are due to be used. Many households keep a list that matches the labels.

If you find something with no label or an unreadable one, decide whether to throw it away. Unidentified food of unknown age is not worth a risk.

What should you know about selling or gifting labeled food?

Selling home-preserved food usually carries labeling rules that vary by state, such as requirements for ingredients, name and address, and sometimes a statement that the food was made in a home kitchen. Rules differ by state and county. Ask your state department of agriculture and local health department what applies before you sell.

For gifts, a simple label with ingredients and date is considerate and helps recipients who have food allergies.

What habits keep labeling easy?

Keep a marker and labels where you work. Label at the moment you fill or seal, not later. Use the same format every time so you can read it quickly. Make labeling part of the cleanup routine. Take a few minutes at the end of each preserving day to check that every item is labeled, entered in your records and put in its place. This habit prevents the mystery jar that nobody can identify months later.
