A house sauce you've served on the plate for years doesn't sell itself out of a jar — the moment it's sealed and put on a shelf, it's legally a different product from the dish it came from, with its own cost stack and its own label.
Almost every owner has thought about it at some point: the sauce guests ask to buy a bottle of, the spice blend regulars want to take home, the recipe the house has made for years that "we really should be selling". It feels like free money — the recipe already exists, the kitchen already knows it by heart, and the guest already asked for it.
But a jar on a shelf isn't a plate with a sticker on it. Both come out of the same kitchen with the same recipe, and yet — legally and financially — they're two completely different products. A plate recovers its cost through the markup on the whole table. A jar has to do that entirely on its own, and carries a labeling obligation the plate has never had to carry.
Seven numbers sharpen that difference: the margin left once the jar carries its own costs, the label that legally needs seven fields where the menu needs one, the minimum order that decides whether a first test run is even practical, the shelf-life test that has to happen before that, the cut each sales channel takes, whether the jar replaces a dinner or sells one, and the breakeven point where all of it lands.
This article doesn't say whether the idea is a good one — only you know that, with your own recipe and your own guests. What it does lay out are the numbers that decide whether it works for YOUR restaurant, including a calculator at the end where you plug in your own price, cost and sales channel.
Why this catches so many owners off guard
Most owners who try this for the first time price the jar the way they price a dish: a markup on the ingredient cost. But a retail product carries a cost structure a plate never has to — packaging, a label, a minimum order at a production partner, sometimes a shelf-life test — and those costs don't disappear because the recipe already existed.
Almost nobody bottling a sauce for the first time also realizes the label falls under a different law than the menu the moment it does. Regulation (EU) 1169/2011 spells out exactly what has to appear on a pre-packaged food item, no matter how small the run — there's no exemption for "it's a small restaurant".
The result: an idea that sounds simple on paper — "we already make this" — usually stalls at one of three places in practice. The margin turns out thinner than expected once every cost is counted, the label takes more time and money than the jar itself, or the breakeven point sits further out than a first, small test run can carry.

Every number below builds on the same starting point: one recipe, two products, each with its own accounting.
1. Two businesses under one roof
A menu price recovers far more than the ingredient cost. The markup on a set table also covers staff, rent, energy and everything else that keeps a service running — at a typical food-cost target of 28 to 32%, gross margin on paper sits around 68 to 72%. That margin is already spoken for before it becomes profit, but it exists because of the whole restaurant around it.
A jar on a shelf doesn't have the rest of the restaurant to lean on. The product has to carry its own full cost stack: not just the ingredients, but the jar, the lid, the label and the labour or service needed to bottle it — with none of the built-in markup a set table gets.
A concrete example: the same pasta sauce costs €18 on the plate, against a food cost of €5.40 (30%) — a margin of €12.60, or 70%. The same sauce in a 350 ml jar, sold at your own till for €8.50, costs €4.00 per unit (ingredients, jar, lid, label and bottling labour combined) — a margin of €4.50, or 53%. Same recipe, a noticeably thinner margin.
Price, cost and margin side by side — the same recipe, two different products.
Figures from the first number above — €18 on the plate against 30% food cost, €8.50 in a 350 ml jar against a unit cost of €4.00 (ingredients, packaging, label and bottling labour combined).
2. The line you cross the moment you bottle it
Regulation (EU) 1169/2011 on the provision of food information to consumers (the FIC Regulation) applies the moment a food item is pre-packaged for direct sale. There's no threshold for small runs and no exemption for an independent restaurant — the law applies to a test run of 200 jars exactly as it applies to a factory.
The gap with the menu is wide. A dish on the menu has, in most EU countries, exactly one legal requirement: state the allergens, often via a symbol or footnote. A jar on a shelf has seven: a legal name for the product, a full ingredient list in descending order by weight, allergens bolded within that list, a nutrition declaration per 100 g or 100 ml (energy plus seven nutrients), the net quantity, a lot or batch number, and a durability date with the operator's name and address.
This isn't a case of sticking a price tag on with a marker. A correct nutrition declaration needs either a lab analysis or a calculation based on validated ingredient data — and most independent kitchens have neither in-house by default. Account for that before the label goes to print, not after.
Regulation (EU) 1169/2011 applies the moment the dish becomes a sealed product — the menu escapes it, the label doesn't.
- Allergens (usually a symbol or footnote)
- Legal name of the product
- Full ingredient list, descending by weight
- Allergens, bolded within the list
- Nutrition declaration per 100 g / 100 ml
- Net quantity
- Lot or batch number
- Durability date, operator's name and address
7 mandatory fields against 1 — and not one of them counts for less because the run is small.
3. The minimum order that decides if it's even practical
A production partner (a "co-packer") that bottles for you almost always works with a minimum order per product — typically somewhere between 500 and 2,000-plus units per run. Below that threshold, a run often isn't worthwhile for the partner, or you pay a noticeably higher price per unit because the machine's setup cost is spread over fewer units.
A handful of EU member states allow limited exemptions for small-scale or artisanal production up to a low annual volume — but a shelf-stable sauce carrying a nutrition claim usually falls outside that in practice, precisely because it carries the full labeling obligation from the previous number.
What that costs in practice: a first run of 500 jars at a co-packer often runs noticeably higher per unit than a run of 2,000 — sometimes a third more — because the machine's setup, cleaning and changeover cost the same regardless of volume. Testing at small scale is itself a cost.
4. What a shelf-life claim costs before you're allowed to print it
A durability date that goes beyond a few refrigerated days isn't a guess — it's a substantiated claim. A claim to sit at ambient shelf temperature needs pH and water-activity levels under specific thresholds; for nearly every other product, a microbiological shelf-life study (a "challenge test") is the standard route.
That kind of test typically costs, depending on the product and the lab, somewhere between a few hundred and over a thousand euros — a one-off cost that belongs in the setup budget alongside the label design, not in the per-unit cost.
Many owners skip this step and sell chilled-only, with a shelf life of a few days. That's a valid, cheaper starting point — but it immediately narrows the reach: no shipping, harder wholesale, a smaller window to sell before the product has to be thrown away.
5. The channel cut
In practice there are three sales channels, and each keeps a different share of the shelf price for itself. At your own till, you keep almost the full price. Selling wholesale to a local shop, that shop pays you a trade price — typically around 50% of what they sell it for. On an online marketplace, you set your own sale price, but the platform takes a commission, usually somewhere between 8 and 15%.
On this article's numbers (a jar at €8.50, unit cost €4.00), that gives a very different picture per channel: at the till you keep €4.50 margin per unit (53%). Through an online marketplace, at a 12% commission, you keep €3.48 (41%). Through wholesale — at that 50% trade price — you keep just €0.25 per unit. Almost nothing.
The reason this surprises so many owners: they think in the shelf price the customer sees, not in what they themselves actually keep. The calculator below shows exactly where that tips over for your own price and cost.
6. Does the jar replace a dinner, or sell one?
A fair concern: a guest who takes a jar of sauce home to cook it themselves might be a guest who would otherwise have come back to eat next week. That cannibalization is real, and it's not something any till report shows you directly.
There's something on the other side of the ledger, too. A jar with your restaurant's name on it sitting in someone's kitchen cupboard for weeks is a form of repeated exposure a menu tucked in a drawer never gets — the same mechanism behind the halo effect: one good impression colours everything that follows.
On day one, that effect can't be proven. Treat the retail line honestly as a marketing cost that happens to be able to pay for itself, not as a guaranteed profit centre — until your own sales figures say otherwise after a few months.
7. The breakeven timeline
Everything one-off — the label design, the shelf-life test from the previous number, and the premium of a first, small production run from two numbers back — belongs in a single setup cost. Everything that recurs per unit — ingredients, packaging, the unit cost from the first number — is a running cost.
The breakeven point is then simple arithmetic: setup cost divided by weekly margin (margin per unit times units sold per week) gives the number of weeks until the investment is recovered — per channel, because the channel cut showed how much that differs.
Enter your own shelf price, unit cost, setup cost and expected weekly sales below. The calculator runs live for each of the three channels, and shows how many weeks it takes to earn back your setup cost.
Run the numbers for your own product
The calculator below uses the exact same formula as the breakeven number above, for each of the three channels at once.
Enter your own figures — it recalculates on every change, so you can see immediately which channel earns back the setup cost first.

Wholesale here assumes a trade price of 50% of your shelf price, a marketplace a 12% commission — both typical EU averages. Ask your own retail partner or platform for their exact rate.
None of these three channels is inherently the right one. Selling at the till asks for nothing extra — no contract, no commission — but only reaches people who already walk in. Wholesale and a marketplace reach new customers, at a price the calculator above just made visible.
Most restaurants that start this way begin at their own till: the highest-margin, lowest-risk channel, and the fastest way to find out whether guests genuinely buy before signing a contract with a shop or a platform.
How to test it without bottling a single case
None of the steps below require committing to a full production run.
This week
- Work out the real per-portion cost of the recipe with the recipe costing tool — that number is the starting point for any retail price, not a guess scribbled on a delivery note.
- Ask two local co-packers for a no-obligation quote on your smallest practical run, including their minimum order.
- Count, over a month, how often a guest asks "can I take some of this home?" — that's your first, free market research.
Before you sell the first jar
- Check the label design against the seven mandatory fields from the second number above — before it goes to print, not after.
- Get a quote for a shelf-life study from an accredited lab if you want more than a chilled label with a short date.
- Enter your own numbers per channel into the calculator above and decide which channel to set up first.
The recipe already existed
What most owners are missing when they start a retail line isn't the recipe — that already exists, sometimes for years. What's missing are the seven numbers above: the margin left once the jar carries its own costs, the label that legally requires seven fields, the minimum order that makes a test run affordable or not, the shelf-life test that comes before it, the cut each sales channel takes, whether the jar replaces a dinner or sells one, and the breakeven point where all of that lands.
None of these seven numbers say "don't do it". They only say exactly where the margin, the law and the breakeven point sit, so the decision rests on what your own price, cost and sales channel actually deliver — not on a gut feeling.
Start small, at your own till, with a product guests have already asked to buy a bottle of — and let the calculator above, not hope, decide when it's time for a bigger run.
