Hi, is there alcohol in white wine vinegar? I was just wondering could I add normal (malt) vinegar to the Mini Pavlova recipe instead?
Our answer
In a meringue recipe, such as Nigella's Mini Pavlovas (from Domestic Goddess and on the Nigella website), the vinegar is added as it helps to stabilize the whisked egg whites and helps the meringue mixture to hold the air whisked in to it. White wine vinegar is made from white wine but during the process of fermentation most of the alcohol turns to acid. However some vinegars may still contain tiny traces of alcohol.
If this is a concern to you then it is fine to use other types of acid for the meringue. We would avoid using malt vinegar or balsamic vinegar as they have a very strong flavour and could affect the flavour of the meringue. Lemon juice is an ideal alternative, or you could use cream of tartar. Both of these should be used in the same quantity as the vinegar.
Vinegar added to the meringue will lower the pH of the egg whites. This acidic environment will also help to stabilize the egg white foam, preventing the meringue from collapsing too much. The acidity helps to unravel the protein and prevent the proteins from binding together too tightly.
If wine vinegars are a problem then there are some alternatives and apple cider vinegar, or cider vinegar, does not have a strong taste and would be a good alternative. Balsamic vinegar should be avoided as its taste is too strong. It is also possible to use lemon juice or cream of tartar as alternatives.
So you could use lemon juice and still have a "plain" meringue. It is also possible to use another mildly-flavoured acid, such as white wine vinegar, (apple) cider vinegar or cream of tartar. The amount you would use would be the same regardless of which alternative you use.
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.

Acids cause these to relax, more like loose strands of hair then tightly wrapped bundles. These are less likely to break when agitated, meaning your meringues will hold more air, making the meringue more stable.
Acid – you can use 1/2 teaspoon of cream of tartar or 1 teaspoon white, apple cider vinegar, or even lemon juice. The pavlova will NOT taste like vinegar, I promise. The acid helps the egg whites hold onto air and, like the sugar, helps prevent the egg whites from collapsing.
Meringue is essentially made with two ingredients: egg whites and sugar. To transform this watery mix into a towering display of white peaks, you'll need to whip it with an acidic element, such as vinegar. Vinegar is the hero that prevents the overbeating of egg whites by making them stable and firm.
