The recipe

Serves 1

Ingredients

Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Prepare

  1. Ensure the chips are not too greasy and have been well drained.

Assemble the sandwich

  1. Take two slices of bread (the heel works best) and butter one side of each slice, then apply ketchup and spread evenly over the buttered side.

  2. Add chips in a herringbone pattern, minimizing gaps; add multiple layers if desired.

  3. Put the two slices together, press the sandwich on a flat surface, and slap it hard several times with an open hand to crush the filling.

  4. Eat immediately.

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

What each ingredient does

Chips
Provide the hot, starchy filling that gives the sandwich its bulk and texture.
Butter
Adds fat and richness and helps keep the bread from soaking up moisture from the chips.
Sliced white bread
Forms the soft outer structure that holds the filling together.

The step that matters

Drain the chips well. Excess oil on the chips soaks into the bread and makes the sandwich soggy and greasy, so draining them first keeps the bread intact.
