What it does

French toast scales by twos. Two slices per serving with an egg each and a splash of milk feeds any table.

The tool above multiplies servings out. Four servings need 8 slices with 4 eggs and 1 cup of milk. The metric match is 237 ml.

Eggs run one per serving. Milk runs a quarter cup each, just enough custard without soggy centers.

Day old bread wins. Stale slices drink custard and hold shape, while fresh soft bread falls apart.

Butter browns the finish. Medium heat with patience beats high flames and pale middles.

How to use

  1. Pick imperial (cups) or metric (ml).
  2. Enter servings.
  3. Read slices first.
  4. Read eggs next.
  5. Read milk and soak day old bread.

Formula

Slices = servings x 2. Eggs = servings. Milk cups = servings x 0.25.
