Pro Tips

Humidity: Meringue absorbs moisture. Avoid making meringue on rainy or humid days (above 60% humidity). It will weep and collapse.
Egg Whites: Room temperature whites whip faster and higher. Separate eggs while cold, then let whites sit 30 minutes before whipping.
Clean Bowl: Any trace of fat (yolk, grease) prevents whites from whipping. Use a glass or metal bowl, wiped with vinegar.

Four egg whites (120g) with a 2:1 sugar ratio need 240g (1.2 cups) of granulated sugar. This yields about 4 cups of meringue, enough for 24 small cookies baked at 225°F for 60–90 minutes.

Five whites (150g) at the Swiss 1.75:1 ratio need 262g (1.3 cups) of sugar. Heat the mixture over a double boiler to 160°F, then whip to stiff peaks. This base becomes silky Swiss meringue buttercream after beating in butter.

3Italian Meringue for Pavlova — 6 Whites

Six egg whites (180g) with Italian meringue at 2:1 need 360g of sugar dissolved in 7.2 tbsp of water, heated to 240°F soft-ball stage. Pour hot syrup into whipping whites for the most stable, glossy pavlova shell.

Frequently Asked Questions

Q

What is the egg white to sugar ratio for meringue?

The standard ratio is 2 parts sugar to 1 part egg white by weight for French and Italian meringue, and 1.75:1 for Swiss meringue. One large egg white weighs about 30g (1 oz), so you need 60g (about 1/4 cup) of sugar per white for French meringue. Swiss meringue uses slightly less sugar at 52.5g per white because the heating process creates more stability without needing as much sugar.

  • French meringue: 2:1 sugar to egg white ratio by weight (60g sugar per white)
  • Swiss meringue: 1.75:1 ratio (52.5g sugar per white) — heated over water bath
  • Italian meringue: 2:1 ratio (60g sugar per white) with hot sugar syrup
  • Each large egg white = 30g (1 oz, ~2 tablespoons)
  • Using superfine sugar helps it dissolve faster and produces smoother meringue

Italian2:160g (¼ cup)Decorating, buttercream base
Q

How many egg whites do I need for pavlova?

A standard pavlova for 8 servings needs 6 large egg whites (180g), 1.5 cups of sugar (300g for French-style), and 3/4 teaspoon of cream of tartar. This yields about 6 cups of meringue, enough for a 9–10 inch pavlova shell. For a smaller pavlova (6 servings), use 4 whites. The key is baking at 250°F for 60–75 minutes, then letting it cool inside the oven.

  • Standard pavlova (8 servings): 6 whites, 300g sugar, ¾ tsp cream of tartar
  • Small pavlova (6 servings): 4 whites, 200g sugar, ½ tsp cream of tartar
  • Mini pavlovas (12 individual): 6 whites, shaped into 3-inch rounds
  • Bake at 250°F for 60–75 minutes until dry on outside, marshmallowy inside
  • Cool in the oven with door cracked to prevent cracking

Q

What is the difference between French, Swiss, and Italian meringue?

French meringue is the simplest: sugar is gradually whipped into raw egg whites. Swiss meringue is heated over a water bath to 160°F before whipping, making it denser and more stable. Italian meringue is the most complex: a 240°F sugar syrup is poured into whipping whites, producing the most stable and silkiest meringue. Italian is the safest since the hot syrup pasteurizes the whites.

  • French: raw whites + sugar — easy but least stable, best for cookies
  • Swiss: heated to 160°F over water bath — smooth, dense, great for buttercream
  • Italian: 240°F sugar syrup into whites — most stable, silkiest, hardest technique
  • Italian meringue is pasteurized by the hot syrup (safest for uncooked use)
  • French deflates fastest, Italian holds shape for hours at room temperature

Q

Why does my meringue weep or collapse?

Meringue weeps (beads of liquid on the surface) from undissolved sugar or humid conditions. It collapses from overbeating, underbaking, or adding sugar too fast. Fix weeping by using superfine sugar and adding it gradually (1 tablespoon at a time). Fix collapsing by whipping to stiff peaks (not beyond) and baking long enough for the center to set.

  • Weeping: sugar not fully dissolved — switch to superfine, add slowly
  • Collapsing: overbeaten past stiff peaks — stop when meringue holds its shape upside-down
  • Humidity above 60% causes meringue to absorb moisture and weep
  • Underbaking leaves the center wet — pavlova should feel dry outside
  • Any trace of fat (yolk, grease on bowl) prevents whites from whipping

Q

How much meringue does one egg white make?

One large egg white (30g) produces about 1 cup of whipped meringue. Four egg whites yield approximately 4 cups, enough for 24 small meringue cookies or a pie topping. The volume increase depends on how long you whip: soft peaks give slightly less volume, while stiff peaks maximize volume. Italian meringue produces about 10–15% less volume than French due to the heavier sugar syrup.

  • One egg white = ~1 cup of whipped meringue (8× volume increase)
  • Four whites = ~4 cups = 24 small cookies or 1 pie topping
  • Six whites = ~6 cups = 1 standard pavlova shell
  • A standard piping bag holds about 3 cups of meringue
  • Italian meringue yields 10–15% less volume than French (denser)
