Egg White Meringue with Sugar Syrup

Introduction

Boiling the sugar syrup to 243°F (117°C) and pouring it into soft-peak egg whites gives you a glossy, stable meringue that holds firm peaks. You can use it for frosting cakes, topping pies, or anywhere you need a meringue that stays smooth and structured.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 10 minutes
• Total Time: 25 minutes
• Servings: 8

Ingredients

• 4 oz (125 ml) water
• 8 oz (250 g) egg whites
• 1 lb (500 g) granulated sugar

Instructions

1. In a saucepan, dissolve the sugar in the water and bring to a boil.
2. Boil the syrup until it reaches 243°F (117°C).
3. While the syrup is boiling, whip the egg whites to soft peaks.
4. While beating, gradually pour the syrup into the egg whites in a steady stream.
5. Continue whipping until the meringue is completely cool and forms firm peaks.
6. Use as desired.

Variations

• Replace the granulated sugar with caster sugar if you want the syrup to dissolve a little faster; the finished meringue stays similarly glossy and stable.
• Cook the syrup to 240°F (116°C) instead of 243°F (117°C) for a slightly softer meringue that spreads more easily as a topping.
• Cook the syrup to 245–248°F (118–120°C) for a firmer meringue that pipes with sharper edges.
• Add a small amount of vanilla powder (use half this amount if you prefer less rich vanilla flavor) after the meringue has cooled if you want a softer, sweeter flavor without changing the texture much.
• Torch the finished meringue after spreading or piping it for a toasted surface and a light caramel note.

Tips for Success

• Keep all yolk out of the egg whites or they may not whip to proper soft peaks.
• Use a thermometer for the syrup; 243°F (117°C) gives you the balance of stability and volume this recipe needs.
• Pour the hot syrup in a thin, steady stream down the side of the bowl so it mixes in instead of hitting the whisk and splattering.
• Stop whipping only when the bowl feels cool and the meringue holds firm peaks; if it is still warm, it can look loose.
• Use the meringue soon after making it for the fullest volume and smoothest texture.

Storage and Reheating

Store the meringue in an airtight container in the refrigerator for up to 24 hours. Press plastic wrap directly against the surface if possible to reduce drying.

Freezing is not recommended. The texture breaks down after thawing and the meringue can separate or weep.

Reheating is not useful for this recipe. If it has been chilled, let it sit at room temperature for 10 to 15 minutes and rewhip briefly to restore some volume.

FAQ

Do you need a candy thermometer for this recipe?

Yes, it helps. The syrup temperature controls the final texture, and guessing can leave you with a meringue that is too loose or too stiff.

Can you use carton egg whites instead of fresh egg whites?

Yes, if they are plain 100% egg whites with no added stabilizers. Fresh egg whites usually give better volume and a more reliable whip.

Why is the meringue grainy?

The sugar may not have fully dissolved before the syrup boiled, or the syrup may have been cooked too far. Make sure the sugar is dissolved first and stop at 243°F (117°C).

Why did the meringue deflate?

The egg whites may have been under-whipped before the syrup was added, or the mixture was not whipped until completely cool. Soft peaks before the syrup and firm peaks at the end are both important.
