How It Works

How to Calculate Meringue Ratios

Formula

Sugar = Egg White Weight x Ratio

Meringue Types

  • Soft meringue (1.5:1): For topping pies. Soft, marshmallow-like texture.
  • French meringue (2:1): Standard ratio for cookies and pavlova. Sugar is beaten into raw whites.
  • Swiss/Italian (2.5:1): Sugar syrup or double-boiler method. More stable, glossier, and safer because the whites are heated.

    • Add a pinch of cream of tartar (about 1/8 tsp per white) to stabilize the foam. Ensure bowls and beaters are grease-free.

    Worked Example

    4 egg whites for a standard French meringue.

    egg_whites = 4meringue_type = 2white_weight = 33
    1. 01Total egg white = 4 x 33 = 132 g
    2. 02Sugar = 132 x 2 = 264 g (about 1.3 cups)
    3. 03Cream of tartar = 4 x 0.5 = 2 g (about 1/2 tsp)

    Frequently Asked Questions

    Why do my meringues weep?

    Weeping (liquid pooling under the meringue) is caused by undercooking. The sugar was not fully dissolved into the egg whites, or the meringue was not baked long enough. Use superfine sugar and check that it is fully dissolved by rubbing a bit between your fingers.

    Can I use a hand mixer instead of a stand mixer?

    Yes, but it takes longer. A hand mixer typically needs 8-12 minutes to reach stiff peaks, compared to 4-6 minutes in a stand mixer. Keep the speed on high and move the beaters around the bowl.

    How do I know when meringue has stiff peaks?

    Lift the beaters out of the meringue. If the peaks stand straight up without drooping, you have stiff peaks. The meringue should be glossy, not dry or grainy. Overbeating makes meringue clumpy and dry.
