Sugar and air. That is basically all a meringue is, yet somehow it is the most stressful thing you can do in a kitchen. You’ve probably seen those glossy, stiff peaks on Instagram and wondered why yours look like sad, weeping puddles or cracked beige rocks. It’s annoying. I’ve been there, standing over a stand mixer at 11 PM, wondering if the humidity in the room is actually out to get me. Honestly, it might be.
The truth about how to make meringues is that it isn’t really about a recipe. Recipes are everywhere. It’s about physics. It is about the specific way protein strands in egg whites uncurl and wrap themselves around air bubbles while sugar stabilizes the whole fragile architecture. If a single molecule of fat from a stray egg yolk or a greasy bowl gets in the way, the party is over. The proteins won't bond. You’ll just have a bowl of soapy-looking liquid that refuses to grow.
The Science of the "Skinny" Egg White
Stop using cold eggs. I know, everyone says eggs separate better when they are cold, and that is true. The yolk is firmer. But if you try to whip cold whites, you’re making it harder on yourself. Room temperature proteins are more elastic. They stretch. You want stretch.
Professional pastry chefs like Pierre Hermé often talk about "aging" egg whites. This sounds fancy, but it just means leaving them in a container in the fridge for a few days so some of the water evaporates. This concentrates the protein. If you’re serious about how to make meringues that actually hold their shape, crack your eggs, put the whites in a jar, and wait twenty-four hours. Or don't. It’s a trick, not a law. But never, ever use the stuff from a carton. Those are pasteurized. The heat process messes with the proteins, and while they might get foamy, they usually won't reach that structural "stiff peak" phase you need for a Pavlova.
The Grease Factor
Your bowl must be surgically clean. Even a fingerprint can have enough oil to ruin the batch. A common pro tip is to wipe your bowl and whisk with a paper towel dipped in lemon juice or white vinegar before you start. This cuts through any invisible residue.
How to Make Meringues Without the Gritty Texture
This is the biggest complaint people have. You take a bite, and it feels like sand. That is undissolved sugar. Sugar is heavy. If it isn’t fully dissolved into the egg white structure, it will eventually sink and cause the meringue to "weep" or leak syrup in the oven.
One way to fix this is to use superfine sugar (caster sugar). If you can't find it, just pulse regular granulated sugar in a blender for thirty seconds. Don't turn it into powder, though. You just want smaller crystals. Another trick, often used in Swiss meringue methods, is to whisk the sugar and whites over a pot of simmering water—a bain-marie—until the sugar melts before you even start the heavy whipping. It feels like more work, but it’s a total insurance policy against graininess.
The Stages of Whipping
- The Frothy Stage: It looks like the top of a latte. Big, loose bubbles. This is when you add your stabilizer, like cream of tartar or a drop of lemon juice.
- Soft Peaks: When you lift the whisk, the foam makes a point that immediately flops over. It looks like a melting soft-serve cone.
- Stiff Peaks: This is the goal. The peak stands straight up like a mountain. It’s glossy. It’s beautiful. If you turn the bowl upside down over your head, nothing should fall out. (Maybe don't try that the first time.)
Temperature Control and the "Low and Slow" Lie
Most people think they are "baking" meringues. You aren't. You are drying them out. If your oven is too hot, the sugar will caramelize, and your white meringues will turn tan. They might even crack because the outside dries too fast while the inside is still expanding.
I usually set my oven to about $200°F$ ($95°C$). If your oven runs hot, go even lower. You want them to sit in there for a long time—often ninety minutes to two hours. And here is the secret: once the timer goes off, do not open the door. Turn the oven off and leave them in there for another few hours, or even overnight. This slow cooling prevents the thermal shock that causes those ugly cracks.

Different Styles for Different Results
Not all meringues are created equal. You've got options.
- French Meringue: The easiest and most common. You just whip whites and slowly rain in the sugar. It’s the most fragile but the lightest.
- Italian Meringue: This involves pouring a $240°F$ sugar syrup into whipping whites. It’s terrifying because of the hot syrup, but it is the most stable. It’s what you use for macarons or to top a lemon meringue pie that won't collapse.
- Swiss Meringue: The middle ground. You heat the sugar and whites together, then whip. It’s dense, marshmallowy, and great for buttercream.
Troubleshooting Common Disasters
If your meringues are chewy, they’re humid. Sugar is hygroscopic, which is a fancy way of saying it sucks moisture out of the air. If it’s raining outside, maybe just don’t make meringues that day. They will act like little sponges and get tacky within an hour.
If they are weeping beads of syrup, you probably added the sugar too fast. You have to add it one tablespoon at a time. Let the mixer do the work. Patience is literally the only ingredient you can't substitute here.
Real-World Examples
Take the Pavlova, the national dessert of both Australia and New Zealand (they fight over it constantly). A Pavlova is just a giant meringue, but it usually has a bit of cornstarch and vinegar added at the end. This gives it a unique "marshmallow" center while keeping the outside crisp. Without that starch, a giant meringue would just be brittle all the way through.
Then you have the "Forgotten Cookies." These are small French meringues mixed with chocolate chips. You put them in a preheated oven, turn the oven off immediately, and forget about them until morning. It’s the ultimate lazy way to master how to make meringues without hovering over the oven light.
Actionable Steps for Your Next Batch
To move from "puddle maker" to meringue expert, change your workflow next time you bake. Start by separating your eggs while cold, then let the whites sit in a clean glass bowl for at least an hour to reach room temperature.
Use a metal or glass bowl—never plastic. Plastic holds onto oil films even after a trip through the dishwasher. When you start whisking, stay on medium speed. High speed creates large, unstable bubbles that pop easily. Medium speed creates a fine, dense "micro-foam" that is much stronger.

Add your sugar gradually, specifically after you've reached the soft-peak stage. If you add it too early, you'll weigh down the proteins. If you add it too late, you'll overbeat the whites, making them grainy and dry. Once they are in the oven, resist the urge to peek. Every time you open that door, you let out the dry air and invite in moisture.
Check for "doneness" by seeing if a meringue lifts easily off the parchment paper. If it sticks, it needs more time. Once they are dry, store them in an airtight container immediately. Not in twenty minutes. Now. This keeps them crisp and prevents that sticky, tacky feeling that ruins the texture.
