How to Prepare Meringue With Meringue Powder

But how does it work? What is the magic formula for using meringue powder instead of egg whites?

Magic Formula

  • 2 teaspoons of meringue powder + 2 teaspoons of water = 1 large egg white

This is a very simple product to work with. All you need is 35 grams of meringue powder, 200 ml of water, 500 grams of sugar, 150 ml of water, and 1 or 2 lemons. Ready to take notes?


  • All you need to do is get your electric mixer, combine water with your meringue powder, and start beating.
  • Meanwhile, you’ll be making a sugar syrup with the sugar, 150 ml of water, and lemon juice.
  • Then, once the sugar dissolves, pour carefully into the meringue foam whisking at high speed. And remember, this step needs to be performed in a slow and steady stream. This process will take you about a minute to pour all the syrup in.
  • After 2 minutes reduce the speed to medium. And there you have it, ready to use!

How to Know if Meringue Powder is Bad

There are many tell-tale signs to look out for to determine whether your meringue powder has gone bad, and is therefore unusable. Let’s take a closer look at these signs.

  • Lumpy. If your meringue powder is starting to lump together, this means that moisture has somehow made its way into the powder. And while it’s safe to eat, it will not do its job effectively at all. Whether it’s all clumped together, or some parts are free from moisture, you should discard it all as it’s unlikely to still work.
  • Smell. If your meringue smells anything other than mild and sweet, it likely means that your meringue powder should be discarded. It may smell sour or slightly acid-like when it’s gone bad, instead of sweet.
  • Color. The color of meringue powder is usually off-white, although this may vary depending on which brand you’re using. If there are any mold spots on your meringue powder, it is unsafe to consume and should be discarded immediately. Another color change is simply fully changing color because of the time it’s been left unused. It’s best to buy new powder as this is unlikely to do its job well, in comparison to fresh meringue powder.

Can You Use Expired Meringue Powder?

When it comes to using expired meringue powder, as long as there are no bad smells or mold spots, it’s probably safe to consume. However, it will likely have lost its effectiveness, and should probably be replaced with fresh meringue powder. As well as this, meringue powder usually contains dehydrated eggs, which you may want to avoid eating past the expiry date; just in case it does make you ill.

How Long Does Meringue Powder Last After Opening?

As long as your meringue powder is stored correctly, it will last around 2 years. It should be stored in a cool, dry place for best results; like a pantry. Moisture is the enemy of meringue powder, so coolness and low humidity are key. Most meringue powder will have an expiration date on the packaging.

How to Read Wilton Expiry Dates

Wilton is the most common option when it comes to meringue powder. However, their expiry date system is slightly different. Instead of an expiration date, they have a manufacturing date added to their meringue powder. You can then safely consume the product for up to two years after that date.

Let’s take a look at how the Julian date code works.



The first two numbers stand for the year (2021) and the next three numbers are the day of the year it was made, out of the 365 days (001 is January 1st).
