Why it works: Potato and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 5,355 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Pancakes
Ingredients
Directions
Prepare
Grate the raw potatoes and let the water drain off a little.
In a bowl, combine the drained potatoes, beaten eggs, salt, and flour.
Heat lard in a skillet over medium heat.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw potatoes
- Provide the starchy bulk that gives the pancakes their body and crisp exterior.
- Eggs
- Bind the grated potato together so the pancakes hold their shape while frying.
- All-purpose flour
- Absorbs excess moisture and helps the mixture bind and brown evenly.
- Lard
- Conducts heat for frying and gives the pancakes a golden, crisp surface.
The step that matters
Fry slowly until golden brown on both sides. Grated potato holds a lot of water and starch. Frying over medium heat lets the centre cook through before the outside burns, while the lard browns the surface through the Maillard reaction.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, flour. Candidates are from the same food group and used in at least 100 recipes.
