Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Hard-boiled eggs
Form the main body of the filling, giving it its creamy, spreadable texture.
Almond meal
Adds body and a slightly nutty flavour, thickening the filling a little.
Lemon juice
Adds acidity that brightens the rich egg and balances its flavour.

The step that matters

Sift the eggs instead of chopping. Chopping leaves firm pieces that tear bread and spread unevenly. Pressing the eggs through a sieve breaks them into fine crumbs that blend smoothly and spread easily.

Swap the almond

How well each one fits the dish's main ingredients (egg, parsley, celery, lemon, bread):

  1. Chickpeafits better
  2. Walnutfits better
  3. Lentilsfits better
  4. Almondthe original

Fit is the average pairing score against egg, parsley, celery, lemon, bread. Candidates are from the same food group and used in at least 100 recipes.
