Flat Meringue Mixture | Ask Nigella.com? ›

If the meringue mixture becomes flat or runny when the sugar is added then it usually means that the egg whites were not quite whisked enough before the sugar was added. It sometimes helps to whisk the whites, then add a tablespoon of sugar and whisk the whites back to medium peaks before adding the rest of the sugar.

Fixing runny meringue is usually as simple as whisking more air into the mixture and waiting for it to develop stiff peaks. You can also add another egg white or a teaspoon of cornstarch to get the mix to the consistency you need.

The cornflour and vinegar that is added strengthens the egg white and make it more stable and you get the marshmallowy centres from the shorter cooking time.

If you add the sugar too quickly then the mixture will never acquire the stiff consistency you want. You also need to be careful if you've used extra ingredients to flavour your meringues. Oils (such as those in nuts or zest) and liquids can stop the egg whites from stiffening, so you have to experiment with amounts.

Cream of tartar stabilizes the tiny bubbles in the egg whites, by precluding the egg proteins from sticking together. It thus speeds up the egg white whipping process and contributes to a stable, billowy, glossy meringue, perfect for cookies, topping pies, and folding into cake.

Over whip the egg whites and you risk making them too firm and they will risk losing the moisture that they hold. This will affect your meringue's crispness, as well as making it more likely to collapse or weep beads of sugar. As my meringue guru Gary Mehigan advises: “If you over whip the egg whites you cannot fix it.

Meringue rules: The final verdict

Abide — Avoid yolks; use a non-plastic bowl; add sugar slowly, and bake low and slow. Let slide — Don't pull your hair out if your eggs are cold, you don't have superfine sugar, or it's a humid day.

Use fresh egg whites. Old egg whites tend to collapse when other ingredients are folded in, and they don't rise well in the oven. Use eggs at room temperature. Cold egg whites tend to reduce meringue volume.

A mild acid will help give your meringue more volume and structure, which means they will inflate more fully and hold the air longer. You don't need much: about 1/4 teaspoon of cream of tartar for every two to three egg whites should do the trick. You can also use lemon juice.

Make sure that no egg yolk is in with the egg whites. Egg yolks are very high in fat and will hinder the whisking process. Cream of tartar is an acidic powder extracted during winemaking. It is used to stabilize egg white foams and increases their heat tolerance.

What if I accidentally got the yolk in my meringue? ›

So, if you accidentally get a little bit of yolk in your whites, do as Dominique Ansel does and add some cream of tartar. It'll help the whites whip up and you won't even taste it.

First, salt promotes the coagulation of proteins, which means you have to beat the egg whites longer to unwind the bunched up (coagulated) protein strands and stretch them into the thin films that encase air bubbles and create foam.

It can be made with any sugar. One cup of superfine sugar or packed brown sugar is equal to 1 cup of granulated sugar; 1-3/4 cups powdered sugar equals 1 cup granulated. Superfine sugar may dissolve more readily and produce a smoother glossier meringue, but volume will not be as great.

To check if the meringue is done whipping, grab the whisk and swirl on the bottom of the bowl. You should feel some resistance against the whisk. If there is no resistance at all, chances are the meringue isn't done whipping. But let's check the other signs.

Hard meringues are not actually baked, but are dried in a 225°F oven for 1 to 1-1/2 hours. They are left in the oven after it is turned off to continue drying without browning. Chewier texture: If you prefer a chewy marshmallow-like center, reduce baking time.

A small amount of cream of tartar or vinegar can be added to the mixture at the beginning of whipping to help stabilize the foam and make it less likely to collapse. Don't use plastic bowls—they can retain a film of fat from previously mixed or stored items that can deflate the meringue.

Acid. Whether it be vinegar, lemon juice, cream of tartar, or a combination, an acid will greatly improve the structure of meringue. Acid not only helps meringue whip up and aerate more quickly, it also keeps it stable. Without acid, meringue is more likely to collapse either during or after mixing.
