Meringue Calculator

Meringue is a ratio, not a recipe. Tell it how many whites you have and what you're making, and get the sugar, stabiliser and method.

One large egg white ≈ 30 g. Ratios are by weight against the whites.

FAQ

Do I need cream of tartar?

Not strictly, but it helps. About ⅛ tsp per white stabilises the foam and makes it far harder to over-whip. A few drops of lemon juice or vinegar does the same job.

Caster or granulated sugar?

Caster (superfine) dissolves faster and gives a smoother meringue. If you only have granulated, add it more slowly, or blitz it briefly in a food processor.

How do I know the sugar has dissolved?

Rub a little between your fingers — it should feel smooth, not gritty. Undissolved sugar is what makes meringues weep syrup beads while baking.
