How to change your menu without breaking your GP
Menu changes affect food cost, stock, and supplier relationships simultaneously. The operations that navigate them cleanly are the ones that plan the transition, not just the new dishes.

Changing a menu is a creative decision and an operational one. The new dishes need to work in the kitchen, the produce needs to be available reliably, and the prices need to produce acceptable margin. Most of the attention goes on the first two. The third — the financial planning that ensures the new menu performs — often receives less thought than it deserves.
A menu change that produces beautiful food but worse GP than the menu it replaced is not a success. Understanding the financial implications before the new menu launches is what prevents this.
Before the new menu: understand where you are
A menu change is easiest to evaluate when you have a clear picture of the current menu's financial performance.
Which dishes produce the highest GP in absolute terms? Which have the highest GP percentage? Which dishes are high-volume and therefore have a disproportionate impact on total food GP? Which are marginal performers that the kitchen puts effort into but that do not produce strong margin?
This information should be available from your recipe costing data. If it is not — if dishes have not been costed, or if costs are out of date — the first step before a menu change is to establish the current baseline.
Without this baseline, you have no way of knowing whether the new menu improves or worsens the financial position.
Costing the new menu before it launches
Every dish on the new menu should be costed before it goes to print.
Recipe costing for a new dish involves identifying all ingredients at the correct yield (raw weight vs cooked weight), applying the current supplier prices for each ingredient, and calculating the total ingredient cost of the dish as specified and portioned.
The target GP percentage for each dish should be known before the selling price is set. Working backwards: if the target food cost is 30%, and the ingredient cost of the dish is £4.50, the minimum selling price to achieve that target is £15. Whether the market will support £15 for that dish is a separate question — but you need to know the number before you can answer it.
Dishes where the ingredient cost requires a selling price that is above what the market supports have one of three solutions: reduce the specification (smaller portion or less expensive ingredient), accept a lower margin on that dish and compensate with volume on higher-margin items, or remove the dish from the menu. All three are valid responses. The invalid response is to launch the dish without knowing the margin impact.
Managing stock through the transition
A menu change creates a stock management problem: old menu items that need to be run down, new items that need to be brought in, and potentially a period where both are in the system simultaneously.
The transition plan should include:
Depletion list. Which current menu items will be removed, and what stock of their key ingredients currently exists? The goal is to arrive at the launch date with minimal remaining stock of ingredients that will not be used after the change. Dishes that use these ingredients should be promoted in the final weeks before the change; the kitchen can be flexible in using remaining stock in staff meals or daily specials.
New supplier relationships. New menu items often require new suppliers or new products from existing suppliers. These relationships need to be established and the first deliveries confirmed before the new menu launches — not during the first service.
Opening stock for new items. What quantity of each new ingredient is needed for the first week of trading? This requires an estimate of early dish volume, which is inherently uncertain. Starting with a conservative stock position and ordering to replenish based on actual demand is safer than over-ordering on the assumption of immediate popularity. Understanding how rising supplier prices affect food costs during this period is worth factoring into your opening order quantities.
After the launch: the first review
The first two weeks of a new menu produce pricing and product data that can be compared against the pre-launch assumptions.
Which dishes are selling at the expected volume? Which are underperforming, and is this a menu position problem (not enough description, wrong placement) or a pricing problem? Which ingredients are depleting faster than the assumed recipe volumes suggest?
The last question is the one that often surfaces problems with recipe specifications or portion compliance. If the beef in a particular dish is costing more than the costed recipe suggests, either the portion is larger than specified or there is more waste in preparation than the yield assumption allowed for.
Catching these issues in the first two weeks, when the new menu is fresh and the kitchen team is engaged, is much more effective than discovering them in the month-end GP and trying to reconstruct what happened.
“We have managed to add about 3% to our blended GP as a business since the introduction of Hops and all the training! Which is better than even I could have ever hoped.”

Hops connects recipe costing to live supplier prices and post-sale consumption so the theoretical GP of a new menu can be compared against what actually happens in the first weeks of trading. Menu changes produce better outcomes when the financial data flows in both directions.
Frequently asked questions
How do I know if a new menu will improve or damage my GP?
Cost every new dish before it goes to print, using current supplier prices and accurate yield figures. Compare the expected food cost percentage of each dish against your targets, and run a rough sales-mix projection to estimate what the blended GP across the new menu will look like. Without this pre-launch analysis, you will only find out whether the menu works at the month-end review.
How do I manage leftover stock when changing the menu?
Build a depletion list before the change: identify which ingredients belong only to dishes being removed, then promote those dishes in the final weeks and use the ingredients in staff meals or daily specials. Arriving at the launch date with minimal dead stock prevents both write-offs and storage pressure. Hops tracks stock against recipes so you can see exactly how much of each ingredient you hold -- hopshq.com.
Should I set selling prices before or after costing a new dish?
After costing. Work backwards from your target food cost percentage: if your target is 30% and the dish costs £4.50 to produce, the minimum selling price to hit that target is £15. Whether the market will support £15 is a separate question -- but you need to know the cost-grounded floor before you can have that conversation.
What should I check in the first two weeks after a menu launch?
Review which dishes are selling at expected volume, whether any ingredients are depleting faster than the recipe quantities suggest, and whether portion compliance is in line with how dishes were costed. Faster-than-expected ingredient depletion usually means the kitchen is portioning above specification or prep waste is higher than the yield assumption allowed for. Catching this in the first fortnight is much more effective than finding it in the monthly GP.
How do supplier relationships affect a menu change?
New menu items often require new suppliers or new product lines from existing ones. These relationships need to be confirmed and the first deliveries arranged before the new menu launches, not during the first service. If you are switching away from an existing supplier for a key ingredient, give them notice rather than simply stopping orders -- goodwill with suppliers matters when prices are rising and reliability is under pressure.
