Making Stable Meringue
A reliable meringue comes down to discipline and cleanliness. If a trace of fat finds its way into your bowl, the proteins will never bond to hold the air you are working so hard to incorporate.
Control your environment and your tools.
Wipe your mixing bowl with a paper towel dipped in white vinegar to remove invisible oil residues. Ensure your egg whites are entirely free of yolk fragments.

What goes in.
- 4large egg whites, room temperature
- 1 cupsuperfine (caster) sugar
- 1/4 tspcream of tartar
- 1/2 tspvanilla extract
The Sugar Incorporation
Do not dump the sugar in at once. Add it one tablespoon at a time only after the whites have reached a soft, frothy stage, allowing the mixer to fully dissolve each addition.
The method.
Prepare the oven
Preheat your oven to 225°F (107°C). Line a heavy baking sheet with parchment paper.
Begin the foam
Beat egg whites and cream of tartar on medium-low speed until they reach the soft peak stage, where the foam holds its shape briefly before curling over.
Incorporate sugar
Increase speed to medium-high. Add sugar one tablespoon at a time. Wait 15 seconds between each addition to ensure the grains disappear into the protein matrix.
Verify stiffness
Continue beating until the mixture is thick, white, and glossy. When you pull the whisk out, it should create a sharp, upright peak that does not droop.
Shape and bake
Spoon or pipe the meringue onto the parchment. Place in the oven and bake for 90 minutes. Turn the oven off and leave the meringues inside to cool completely for another hour.
Other turns to take.
Coffee Meringue
Fold in one teaspoon of finely ground espresso powder at the very end of the whisking process.
Chocolate Swirl
Gently fold two tablespoons of unsweetened cocoa powder into the stiff meringue using a spatula just before piping.
When it doesn't go to plan.
Test for graininess by rubbing a small amount of the mixture between your thumb and forefinger; if it feels gritty, keep beating.
Avoid making meringue on humid or rainy days, as the sugar will absorb moisture from the air and cause the final product to turn sticky.
Using superfine sugar is non-negotiable; standard granulated sugar takes too long to dissolve and can lead to a coarse texture.
The ones that keep coming up.
Why did my meringue crack or weep?
This usually happens if the sugar was added too quickly or if the meringue was cooled too rapidly after baking.
Can I use plastic bowls?
Avoid them. Plastic is porous and often retains a thin layer of grease from previous use that will prevent the egg whites from foaming correctly.
