Moderate — noticeable differences, use with care

Recipe Adjustment Notes

Works where the whites add liquid and protein, not where they must whip. Never substitute whole eggs in meringue — the yolk fat prevents the foam from forming.

The Science Behind This Swap

Yolk fat coats the ovalbumin proteins and blocks the air-trapping network, so whipped volume collapses. In cakes and custards, the swap only changes richness.

Measurement Variance Note

For 1 cup references, this ingredient can vary by about 6% across brands and measuring methods (228g-258g per cup). For the most reliable substitution result, measure by weight and test a half batch first.
