Most recipes are written for four, and most nights you're cooking for two, or for eight. Knowing how to scale a recipe sounds like a math problem, and if you do it by hand it often becomes one: three-quarters of a cup times one and a half, a single egg cut in half, a grocery list that still says the original amounts. This guide walks through the whole procedure, from a saved recipe to scaled quantities to a shopping list that matches what you're actually making.

What you'll have when you finish

In about ten minutes you'll have a recipe resized to the number of people you're feeding, a quick sanity check on the amounts that don't split cleanly, and those scaled ingredients sitting on one grocery list. We'll use MiseMate, where ingredient scaling, grocery lists and Cook Mode are all free, so you never have to do the fraction math yourself.
  • An iPhone with MiseMate installed
  • One recipe you want to make: a link from a food site, a photo of a cookbook page, or one of the app's built-in recipes
  • The number of servings you actually need tonight or this week
  • A rough idea of your pan sizes, since scaling changes how much food has to fit in them

When you need to scale a recipe

Three situations come up again and again. Cooking for two from a recipe written for six, which means either shrinking it or committing to leftovers. Feeding a crowd, where a dinner for four has to stretch to ten without anyone noticing. And meal prep, where you deliberately multiply a recipe so Sunday's cooking covers several lunches. Each one starts the same way: you know how many people you're feeding, and the recipe disagrees.

Why scaling by hand goes wrong

The arithmetic itself isn't hard. The trouble is doing it a dozen times in a row, in your head, while the onions are already in the pan. Odd amounts like two-thirds of a cup or a teaspoon and a half get rounded differently each time. Ingredients that come in whole units, like eggs or cans, don't divide neatly. And even when you get every number right, you still have to rewrite your shopping list, which is where the original quantities quietly sneak back in. Letting the app handle the multiplication leaves you free to focus on the few amounts that genuinely need judgment.

How to scale a recipe in MiseMate, step by step

Step 1: Get the recipe into MiseMate

Import the recipe from its web link or a photo of the page, or pick one from the built-in collection or the online search. If you haven't imported a recipe before, our guide to saving recipes from websites and photos on iPhone covers it in detail. Once it's saved, open it so you can see the full ingredient list.

Step 2: Check how many servings the original makes

Before changing anything, note the serving count the recipe was written for. This is the baseline everything gets scaled from, so if an imported recipe has it wrong or missing, fix that first. A recipe that really feeds six but says four will leave you short every time.

Step 3: Set the number of servings you're cooking for

Use the recipe's ingredient scaling to change the servings to the number you need, whether that's two for a quiet weeknight or ten for a birthday. The ingredient amounts update to match, so you're reading the quantities for your version of the dish rather than the author's. Nothing to multiply, nothing to write in the margin.

Step 4: Read through the scaled list for awkward amounts

Scan the new quantities once, top to bottom. Look for anything that doesn't make sense in a real kitchen, like half an egg, a fraction of a can, or a pinch that has turned into something huge. Decide how you'll handle those now: whisk the egg and use half, buy the full can and save the rest, or season by taste instead of by the number.

Step 5: Send the scaled ingredients to your grocery list

Add the recipe's ingredients to your grocery list from the scaled version, so the list reflects what you're actually making. Check it against your pantry and remove anything you already have. If you're shopping for several recipes at once, add them all before you head out so everything lands on one list.

Step 6: Cook from the scaled version in Cook Mode

When it's time to cook, open the recipe in Cook Mode and follow it step by step with the built-in timers. Keep in mind that the timers come from the recipe as written, so a doubled pot or a deeper pan may need longer, and a halved batch may finish sooner. Start checking for doneness a little early and adjust from there.

Getting the scaled amounts onto one grocery list

The payoff of scaling inside the same app you shop from is that the numbers never get retyped. You resize the recipe, add it to the list, and the list already says two pounds instead of one. If you want to go deeper on building and organizing the list itself, see how to turn any recipe into a shopping list in minutes. And if you're scaling several dinners for the week, Premium's meal planning calendar lets you lay them out first, which pairs well with our guide to using a weekly meal planner on iPhone and shopping once.

What scaling can't fix: time, pans and seasoning

Some parts of a recipe don't move in a straight line, and no app can decide them for you. Pans: a doubled recipe usually needs a bigger dish or two batches, and a halved one may need a smaller pan so it doesn't dry out. Time: more food takes longer to heat through, and less food finishes sooner, so watch rather than trust the clock. Seasoning: salt, chili and strong spices can taste heavier when multiplied, so start with a bit less than the scaled amount and add to taste. Baking: leavening and pan depth matter more here, so when in doubt, make two batches at the original size.

Common questions

Can I scale a recipe I imported from a photo or website?

Yes. Once a recipe is saved in MiseMate, whether you imported it from a link, a photo, or picked it from the built-in collection, you can scale its servings up or down. Just check that the original serving count came through correctly after import, since that's the baseline for scaling.

Is recipe scaling free in MiseMate?

Yes. Ingredient scaling is part of the free core features, along with recipe browsing, grocery lists and Cook Mode. Premium adds the AI kitchen assistant and the meal planning calendar.

What if I'm short on an ingredient after scaling up?

With Premium, MiseMate's AI kitchen assistant can recommend substitutions for an ingredient you don't have enough of, or suggest recipes based on what's already in your pantry. Without it, check your scaled list against the pantry before shopping so you catch shortfalls in the store instead of mid-recipe.

Does a halved recipe cook in half the time?

Usually not exactly. Smaller amounts often finish sooner, but the relationship isn't neat, and pan size has a big effect. Use the recipe's timers as a guide and start checking for doneness early.

How do I choose an app that handles scaling and shopping together?

Look for one where scaling, grocery lists and cooking all happen on the same recipe, so amounts never need retyping. Our guide on what to look for in a recipe and meal prep app for iPhone covers the features worth comparing.
