A recipe explainer · from six recipes, normalized
What makes a canelé custardy.
I normalized six popular canelé recipes to percentages of total batter weight to find what decides the interior. One number does most of the work.
The one idea
Flour, as a percent of batter, is the lever between custardy and cakey. Everything else is richness and color.

The number
9–14% flour, as a share of total batter, for a custardy interior — above ~15% it turns cakey and bread-like
← more custardy · soft, fragile
15%
cakey · firm, bread-like →
flour 9%flour 18%
Across the six recipes, the ones people call "custardy" sit at 9–14% flour. Push past 15% and the crumb sets up firm. The recipe I use lands at the high end and leans on fat to stay rich rather than dry.

What each part does
Flour
Structure. More = cakey and firm; less = custardy but fragile. The main lever.
Sugar
Sweetness and caramelization. More = a darker shell; less = paler, less caramel.
Fat
Butter, cream, yolk fat → richness. The lean recipes taste custardy but hollow. Fat is flavor.
Egg
Yolks bind and emulsify for a rich set; more whole egg makes it sturdier but less silky.
