Why it works: Parsnip and flour match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 669 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Fry Parsnips
Ingredients
Directions
Prepare
Boil the parsnips until tender, then mash them well.
In a bowl, beat the eggs and mix in flour, baking powder, and salt.
If the parsnips are not sweet, add some sugar to the mixture.
Fry
Form the mixture into cakes and fry them in hot lard until golden brown.

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
- Parsnips
- Provide the main body and sweetness of the cakes once mashed.
- Eggs
- Bind the mashed parsnips together so the cakes hold their shape.
- Flour
- Adds body to the mixture so it can be formed into cakes.
- Baking powder
- Releases gas that lightens the cakes as they cook.
- Lard
- Conducts heat for frying and browns the outside of the cakes.
The step that matters
Fry the cakes in hot lard until golden brown. If the lard is not hot enough, the cakes absorb more fat and turn greasy before the outside browns. Hot fat sets the surface quickly, helping the cakes keep their shape and develop even colour.
Swap the parsnip
How well each one fits the dish's main ingredients (egg, flour, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Shallotfits better
- Parsnipthe original
Fit is the average pairing score against egg, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
