The Sauce That’s Quietly Eating Your Margin

When you work out what a dish costs, you count the things you buy. The protein, the bread, the cheese — they’re on an invoice, so they’re easy to point at. The things you make tend to vanish from the math entirely. The garlic sauce, the tahini, the marinade, the spice mix, the dressing whisked up fresh every morning. They never appeared on a supplier slip as a finished product, so they quietly never got a price.

That’s the sub-recipe leak. And on a lot of menus it’s bigger than anyone thinks, because the cost doesn’t live in any one sauce — it lives in how many of them stack onto a single plate.

Why the made-in-house stuff slips through

A sauce feels free. You already bought the garlic, the oil, the tahini — those are just “supplies.” So when you picture the cost of a dish, the sauce is a rounding error in your head, if it’s there at all.

But a sauce is a recipe like any other, and it has a real per-kilo cost the moment you actually build it out. Here’s one from a kitchen we costed. Their garlic sauce — the classic whipped garlic, oil, salt, citric acid — comes out to a 5.71 kg batch costing $14.53, which is $2.54 a kilo. Their tahini sauce runs richer: yogurt and tahini push it to $4.87 a kilo.

Per dish, those numbers look harmless. A wrap might carry 25–30 grams of garlic sauce — that’s about 7 cents. You can see why nobody bothers to count it. Seven cents.

The leak isn’t one sauce — it’s the stack

Here’s where it turns into real money. That same wrap doesn’t carry one sauce. It carries garlic sauce, and a little tahini, and a hot sauce, and maybe comes with a garlic dip cup on the side. Each one is a few cents. Counted together, on the actual dish we looked at, the sauces and dips added up to a real line in the cost — and a garlic dip cup served on the side was nearly 40 cents on its own, because a cup is a much bigger pour than a smear inside a wrap.

None of those got counted when the owner set the menu price, because none of them came on an invoice as “sauce.” They came in as garlic, oil, yogurt, tahini — raw supplies — and then disappeared into the kitchen. The dish was priced as if the sauces were free. They are not free. They’re a stack of small, real costs, multiplied across every plate that goes out.

And it compounds the way the others do: the day your supplier’s tahini or oil price moves, every sauce that uses it gets more expensive, and every dish carrying those sauces moves with it — silently, because you were never tracking the sauce in the first place.

How to find it yourself

You don’t need software for one pass at this. You need to actually cost your sauces — once.

  1. List every sub-recipe you make in-house. Sauces, dips, marinades, spice blends, dressings, anything you produce rather than buy finished. Most kitchens are surprised how long this list is.
  2. Cost one batch of each. Add up what every ingredient in the batch costs at today’s prices, total it, and divide by the batch weight to get a cost per kilo. Do this once and you have a number you’ll use forever.
  3. Figure out how much goes on a dish. Weigh a normal portion of each sauce as it’s actually served — the smear inside the wrap, the dip in the cup. Multiply by the per-kilo cost. Now you have the real per-dish cost of each sauce.
  4. Add up the stack on your top dishes. For each of your big sellers, total every sauce and dip it carries. That’s the number that was missing from your dish cost — and it’s almost always more than the rounding error you assumed.

What to do once you’ve found it

If the stack turns out to be quietly heavy, the fix order is the same as always — and notice repricing is last:

  1. Check the portion of the sauce, not just the protein. A garlic dip cup that’s a 40-cent pour when a 20-cent pour would satisfy the customer is the same over-portioning leak we wrote about with protein, just in a different container. Right-size the pour first; it’s free.
  2. Look at the sauce’s own ingredients for a supplier fix. If the tahini or oil that drives the sauce cost has crept up, that’s a supplier conversation — the same lever, one layer down.
  3. Reformulate the sauce, gently. A sauce often has more room to rebalance than a main ingredient does, because the customer is tasting the whole dish, not auditing the sauce. Where a small change holds the flavor and trims the cost, take it.
  4. Reprice — last. Only if the pour’s right, the inputs are fair, the recipe’s as tight as it can be, and the dish still doesn’t earn.

The honest catch

Costing your sauces once is genuinely worth the afternoon. But sauces are built from ingredients whose prices move, which means the number you work out today is right today and slowly wrong after that. Every time the oil or the tahini or the yogurt price shifts, every sauce made from it shifts, and every dish carrying those sauces shifts — and now you’re not tracking one moving number, you’re tracking a web of them.

That’s the whole reason Mise exists. We cost your sub-recipes the same way we cost your dishes, from the prices you’re actually paying — so when the tahini goes up, every sauce that uses it updates, and every dish carrying those sauces updates, automatically. The stack stays counted, even as the inputs underneath it move.

But you don’t need us to start. List your sauces, cost one batch of each, and add up the stack on your three biggest dishes. You’ll likely find a line you’ve been giving away for free. If you want it kept current as the inputs move — see what your menu actually costs →
