Ingredients
Directions
Prepare
Mash the boiled potatoes with hot milk, melted butter, and salt until creamy.
Form the mixture into egg-shaped rolls.
Dip the rolls in cracker dust, then in the beaten egg.
Fry
Fry in deep hot lard until golden brown.
Test the oil temperature with a small piece of bread.
Alternatively, brown the croquettes in a spoonful of butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled potatoes
- Provide the starchy base that mashes smooth and holds the croquette shape.
- Hot milk
- Adds moisture and softens the mash so it stays creamy and easy to shape.
- Butter
- Adds richness and fat, giving the mash a smoother texture and flavour.
- Beaten egg
- Binds the coating so the cracker dust adheres and forms a crisp outer layer.
The step that matters
Test the oil temperature with a small piece of bread.. If the lard is too cool, the croquettes absorb grease and turn heavy; if too hot, the outside browns before the centre heats through. Testing helps keep frying at a steady temperature.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, egg):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against milk, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
