Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 6,805 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Contains: milk, wheat, peanut (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the bread
Cut the rye bread into slices.
Toast the slices in a 350°F oven until golden brown.
Soak the toasted bread in water until soft.
Press out the water.
Make the peanut base
Add the ground peanuts, chopped onions, chopped celery, parsley, salt, oil, and cayenne pepper. Mix thoroughly.
Transfer the mixture to an earthenware dish.
Press the mixture down well.
Make an opening in the center large enough to hold the filling.
Fill and bake
In a bowl, combine the peanut butter, Neufchatel cheese, and milk.
Fill the opening with this mixture.
Cover the filling with the removed portion of bread.
Bake in a 350°F oven for one hour. Serve with ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye bread
- Soaked and pressed, it forms the soft, moist body of the loaf.
- Ground raw peanuts
- Provide the bulk and nutty flavour that forms the main body of the dish.
- Peanut butter
- Adds richness and fat, giving the filling a creamy, spreadable texture.
- Neufchatel cheese
- Adds creaminess and tang to the filling, helping it stay soft and smooth.
- Eggs (in the method)
- Not listed in the record; omitted.
The step that matters
Pressing out the soaked bread. Soaked bread holds a lot of water; if it is not pressed well, the mixture stays wet and loose and may not hold its shape when baked.
Flavor stand-ins for the peanut
How well each one fits the dish's main ingredients (rye, bread, onion, celery, parsley, pepper, butter):

- Peanutthe original
Fit is the average pairing score against rye, bread, onion, celery, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
