Cold Roast Fowl, a LA Mayonnaise

Ingredients

Directions

Prepare the fowl

  1. Roast the fowl until cooked, then let it cool.

  2. Cut the fowl into joints and stack them in the center of a serving dish.

Arrange the dish

  1. Halve the lettuce and arrange it around the fowl as a border.

  2. Wash the watercress and place it around the lettuce.

  3. Cut the hard-boiled eggs in half and place them with the whites facing up among the lettuce and watercress, or cut them into rings for a decorative effect.

  4. When ready to serve, cover the fowl with mayonnaise dressing.

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

What each ingredient does

Fowl
Provides the main cooked meat, which is roasted, cooled and carved into joints.
Mayonnaise dressing
Adds moisture, richness and fat that coat the cold meat and give it a smooth finish.
Hard-boiled eggs
Add firm, mild egg whites and yolks as a decorative and textural contrast to the meat.

The step that matters

Let the fowl cool fully before dressing. Mayonnaise is an emulsion of oil and egg that can separate or turn greasy and runny when spread over warm meat. Cooling the fowl first keeps the dressing thick and stable and lets it cling to the surface.

Swap the lettuce

How well each one fits the dish's main ingredients (egg, watercress):

  1. Horseradishfits better
  2. Chivefits better
  3. Welsh onionfits better
  4. Lettucethe original

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