Why keep records?
Preserving involves many details: the food, the recipe, the equipment, the date and the result. Memory fades fast, and months later you may not recall which recipe you used. Records let you repeat successes, avoid repeated mistakes and respond if a recipe turns out to have a problem.
They also help with planning. If you know how many jars of tomatoes you used last year, you know how many to make this year. Records need not be elaborate. A few lines per batch are better than a beautiful system that you abandon. If you are new to preserving, begin with a simple list and add columns as you see what is useful. Over time your notes become your own tested reference, and you will find that you rely on them more than on memory.
What should you write down?
For each batch, record the date, the food, the amount of raw food you started with, the tested recipe source, the method, the equipment and the number of units produced. Note anything unusual, such as a failed seal, a change in the produce or a problem with the equipment.
Add notes on taste and quality when you open the food later. That feedback is the most useful record for improving. If you preserve with other people, such as a relative or a neighbor, agree on one record system so entries are not split between notebooks. Include their names so you know who handled each batch.
- Date, food and quantity
- Recipe source and method
- Equipment used and any issues
- Results: jars or bags produced, seal failures, quality notes
What format works best?
Use whatever you will keep up: a bound notebook, a binder with printed forms, a spreadsheet or a notes app. A notebook in the kitchen is hard to forget. If you use a computer, back it up.
Keep entries brief and consistent. A simple table with the same columns each time is easy to scan. Consider keeping a master list of your tested recipes, with the source, edition or date of the guidance and any notes. When a source updates its recommendations, you can compare and see which recipes are affected. Keep printed copies of key recipes with your records so that you can use the same version each time.
How do records support safety?
If a tested source later issues a correction or an updated recommendation, your records show which jars were made with the old method. You can then check the guidance and decide what to do. Without records, you may have to discard everything or guess.
Record the details of any equipment check, such as a pressure canner gauge test, so you can see when the next one is due. Add a short note whenever something unexpected happens, such as a power cut in the middle of a batch, a change in produce quality or a piece of equipment that behaved oddly. When you review your records, those notes explain results that would otherwise be a mystery. They are also the best material to bring when you call your extension office with a question.
How do records help with inventory and planning?
Combine your batch records with an inventory of what is on the shelf. At the end of the season, compare what you made with what you ate. That shows which items were popular and which were not. Use it to adjust your garden plan and shopping.
Records of costs, such as jars, lids, produce and fuel, let you build a realistic budget. Do not rely on guesses about what preserving saves.
How long should you keep records?
Keep records at least as long as you keep the food they describe, and longer if they help you plan. Many people keep a few seasons of notes. Ask your extension office whether they have recommendations. Store the notebook where it will not get wet or sticky in the kitchen. At the end of each year, review your records and write a short summary: what worked, what failed and what you want to change. Keep the summary at the front of your notebook and read it before the next season begins.
What if you sell or give away food?
If you sell, rules may require records of ingredients, batches and sources, and rules vary by state and county. Ask your state department of agriculture and local health department what you need to keep. Good records also help you trace any problem back to a batch.
Key takeaways
- Record date, food, recipe source, method, equipment and results for each batch.
- Use a format you will actually keep up.
- Records let you respond to updated safety guidance.
- Check state rules on records if you sell any preserved food.
