Meringue kisses

Meringue is nothing more than sweetened air. The secret to this seemingly simple sweet is stabilising the proteins in egg whites. When we whisk the foam, we are actually wrapping millions of tiny air bubbles in a protein net. During slow baking at low heat - or rather drying - the water evaporates while the sugar structure solidifies, creating the characteristic crisp texture.

Instructions

1

Preheat the oven to 100°C. Wipe the mixing bowl and whisk with a little vinegar.

Tip: Even the smallest amount of fat prevents the foam from whipping up because fat molecules destroy the forming protein network.
2

Start whisking the whites with the salt on low speed, then when it starts to foam, add the vinegar/lemon juice.

Tip: Acid helps proteins form a more stable structure, so the foam doesn't collapse as easily (aiding protein denaturation).
3

Increase speed and add the sugar a spoonful at a time. Whisk after each spoonful until the sugar has completely dissolved (not gritty under your teeth).

Tip: If you pour the sugar in all at once, the foam might collapse. Gradual addition ensures a stable structure.
4

When the foam is glossy, thick, and holds stiff peaks on the whisk, carefully fold in the vanilla.

Tip: Over-whisking after adding sugar is rarely an issue, but work carefully due to the liquid content of the vanilla.
5

Fill a piping bag with the mixture and pipe mounds onto a baking tray lined with baking parchment.

Tip: Try to hold the piping bag vertically for nice shapes.
6

Place in the oven for 90-120 minutes. It is ready when it easily lifts off the paper and the bottom sounds hollow when tapped. Leave to cool in the switched-off oven.

Tip: We are drying, not baking. It can collapse from sudden temperature changes, so it needs to cool slowly.

Recipe FAQ

Why did the meringue become sticky?
Humidity in the kitchen was likely high, or it didn't dry out enough. Sugar absorbs moisture from the air.
Why did it crack?
You baked it at too high a temperature, and the inside expanded faster than the outside could set.
