In short
- For an English producer selling homemade strawberry jam, the published jam rules specify at least 350 g of fruit used per 1,000 g of finished ordinary jam, and 450 g for extra jam. Check the full composition and labelling requirements as well: reaching the fruit minimum alone does not release a recipe for sale.
- Calculate fruit against the finished product yield, rather than the weight of the uncooked pan contents.
- The jam-specific sugar declaration uses soluble solids determined by refractometer; added sugar weight alone is not that result.
- This guide uses England’s rules. Check the applicable national rules for Scotland, Wales or Northern Ireland and any export market.
- AirPost is a peer-to-peer fulfilment network: online shops have their orders packed and dropped at a parcel point by verified people near their customers, who earn a fee per parcel from home. No warehouse, no minimum order volume.
Your farm produces berries and you want to sell jars through a website alongside the fresh crop. A family recipe and a neat label are a starting point, but they do not establish the product’s legal description or the figures printed on it. Make a recipe file before offering the jar. It should connect the fruit you prepare, the jam you finish, the information on the label and the variant that a customer buys online. This is a producer’s workflow, not a preserving recipe.
Does a small online batch still need a product-name check?
The government composition guidance says jams and similar products must comply with reserved descriptions under the Jam and Similar Products (England) Regulations 2003. Ordinary jam, extra jam, jelly and marmalade are descriptions with different requirements. Homemade or farm-made does not replace the legal product name. Choose the intended description before approving the recipe, so the name is tested against the actual product rather than chosen after cooking.
Describe your ingredients and processing to the person assessing the recipe. Note the fruit species, whether pulp or purée is used and any additional ingredients. A mixed-fruit product should not borrow the answer for a single-fruit jar without checking its own category. Keep the assessment with the recipe version. If you later change the fruit or use a supplier preparation instead of your own harvest, review the name before selling that version.
The food-business guidance covers home and online operations and asks new businesses to register at least 28 days before trading. Registration does not approve your recipe or its shelf life. Ask your local authority which food-safety and trading-standards checks apply to the operation you describe. Keep the product-name decision distinct from the assessment of premises, process and storage, because each answers a different practical question.
Which weight belongs in the fruit-content calculation?
Use the appropriate fruit input and the weight of the finished jam. The published England regulations, Schedule 1, set fruit quantities per finished product. Their ordinary-jam minimum for fruits such as strawberries is 350 g per 1,000 g; the corresponding extra-jam figure is 450 g. Some species have different minima. The extra-jam definition also restricts certain fruits, including apples, from being mixed with others. Read the category that actually fits your recipe.
The working formula is fruit used divided by finished jam yield, multiplied by 100. The strawberry minima above therefore correspond to 35 g and 45 g per 100 g of finished product. This is arithmetic from the published thresholds, not a sample production volume. Record your real weights after the relevant preparation steps. A weight taken before removing unusable parts cannot automatically be treated as the fruit quantity used in the product.
| Record | Why it matters | Common mismatch to catch |
|---|---|---|
| Fruit species and preparation | Selects the applicable composition requirements | Using one general minimum for every fruit |
| Fruit actually used | Provides the relevant input for the calculation | Counting discarded material as recipe input |
| Finished jam yield | Provides the denominator | Using uncooked ingredients as finished output |
| Measured soluble-solids result | Supports the specific sugar declaration | Replacing a measurement with added sugar weight |
| Approved label and jar size | Connects the result to the sale unit | Printing an earlier recipe’s figures |
Keep losses and output records consistent. Decide how you account for samples, residues and rejected jars in the documented method used for your product assessment. Do not alter a denominator merely to reach a minimum. If a trial produces an unexpected yield, investigate the actual process before changing the label. A calculation is useful when another person can reproduce it from the retained batch record and understand which measured quantities were included.
Why is the sugar statement different from sugar added to the pan?
Regulation 5 uses soluble solids determined by refractometer at 20 °C for the jam-specific total-sugar statement. It also places the fruit and sugar declarations in the same field of vision as the product name. Treat that measurement and layout as separate checks. Your ingredient sheet tells you what was added; it does not by itself produce the specified finished-product reading. Ask the responsible assessor about the applicable composition conditions and any permitted exception.
Keep the instrument method, calibration checks and batch result in your production record. Follow the appropriate instructions for the instrument and sample. A handwritten number without a method is hard to assess later, particularly if two people measured the same recipe differently. Do not infer a food-safety conclusion from the reading alone. The process, packaging and shelf-life assessment must still support the product you intend to sell.
A lower-sugar variant needs a fresh assessment rather than a quick edit of the ordinary jar’s description. Review the reserved name, any nutrition claim, the declarations and the validated process together. Keep its stock and label separate from the original variant. A customer choosing a different recipe online should receive that actual recipe with its approved information. Using a similar front label for both variants can hide a mistake at the packing bench.
What belongs on the jar before the product page goes live?
The government labelling guide lists general particulars including food name, net quantity, ingredients where required, relevant dates, storage conditions and the responsible business details. Jam has additional product-specific requirements. Review the complete label rather than treating the fruit statement as the whole checklist. Use the actual jar and final printed label when checking the result; a design preview can hide text around the curve.
Separate net quantity from the weight of the filled jar including glass and lid. Keep the filling controls and quantity assessment in your production process. The general guidance says relevant quantity information must be visible with the food name. Lay out the label so the required information can be read as intended. A back-panel redesign can affect this even when the figures themselves have not changed.
Give each approved label a version and associate it with the relevant recipe and pack size. Before using a new print run, compare it with the approved file. When you have different jar sizes, check both layouts instead of shrinking one indiscriminately. Keep unused old labels away from the current packing supply. The person applying labels should select a released version, not decide which recipe the numbers probably describe.
How does the online offer stay connected to the production batch?
Create a product card containing the approved name, concrete flavour, pack size and required food information. Use it to prepare the web listing. Check the purchase route as well as the full product page: quick-buy buttons, gift selections and repeat purchases may use different screens. The customer should be able to identify the variant being purchased. An attractive photograph of a group of jars can accompany the details, but cannot explain them by itself.
At release, compare the online information with the actual jar. Confirm that the flavour and recipe version agree, that the correct label is applied and that the identifying batch information is available. Store the release record with the production records. Keep unreleased jars out of the stock available to fulfil orders. This avoids a rush in which the website sells a batch before somebody has completed its recipe and information checks.
When your own fruit runs out and you buy from another grower, revisit the claims and recipe records that change. Farm-made does not necessarily mean every ingredient was grown on your farm. Use precise descriptions supported by your supply and production records. Tell the person reviewing the product about the change before reusing the existing label. A new ingredient source can matter even when the customer-facing flavour name stays the same.
What does parcel preparation add to the cost of a released jar?
Food production, product release and parcel preparation are different tasks. Budget ingredients, processing, jars, labels and rejected units with your actual costs. Then assess the outer packaging for your real sale unit and any multi-jar set. Ask the relevant delivery provider about product suitability and booking conditions. A price for an ordinary parcel does not validate the food process, establish a shelf life or guarantee that a glass jar will survive its chosen packaging.
For a separately assessed eligible small non-perishable parcel, AirPost’s recommended preparation is €2.25 and the platform fee is €0.85. That gives €3.10 before the carrier label, packing material and stock transport. Source: AirPost price constants, retrieved 14 October 2026. The benchmark is in euros; it is not a sterling checkout charge. Replace the recommended preparation with the actual agreement when budgeting.
AirPost excludes perishables. Assess the concrete finished goods, storage and handling before considering local fulfilment; this is no automatic approval for homemade food or for a refrigerated spread. Keep food production with an appropriately assessed operator. For the separate parcel worksheet, read average shipping cost per order. Count the full work needed to supply a released sale unit, rather than treating the parcel component as the cost of making jam.
Frequently asked questions
Can I sell homemade jam online in the UK?
You need to meet the requirements for the actual food operation, recipe, label and selling method. This article uses England’s product rules. Register and discuss the proposed operation with your relevant authority; check the national rules if producing elsewhere.
How much fruit must homemade strawberry jam contain?
The published England schedule specifies at least 350 g used per 1,000 g finished ordinary jam and 450 g for extra jam. Check the complete category, including other composition conditions. Other fruit species can have different minima.
Do I calculate fruit content from the raw mixture?
The statutory comparison uses finished product. Retain the relevant prepared-fruit input and actual finished-yield records so the calculation can be reproduced. Do not substitute the uncooked pan weight for the finished jam denominator.
Can I calculate the jam sugar statement from sugar added?
That addition is not the specified finished-product measurement. The published regulation uses soluble solids determined by refractometer. Keep the method and result with the batch and review the relevant composition and declaration requirements.
Does using a parcel service approve my jam for sale?
No. Product composition, food safety, shelf life and labelling must be assessed separately. AirPost excludes perishables and requires the concrete goods and handling to be suitable; a parcel benchmark is not food-production approval.
