Name: Parsnip Fritters
Ingredients: 3 parsnips, boiled and mashed; 2 eggs, beaten; 2 tablespoons butter; ½ cup milk; salt to taste; flour, enough to make a thin batter

Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Parsnip Fritters

Ingredients

Directions

Prepare the batter

Boil and mash the parsnips until fine.
In a bowl, combine the mashed parsnips, beaten eggs, butter, milk, and salt.
Add flour gradually until the mixture forms a thin batter.

Cook

Heat a buttered griddle over medium‑high heat.
Drop spoonfuls of the batter onto the griddle and cook until golden brown.

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

What each ingredient does

Parsnips: Provide the bulk and mild sweet flavour of the fritter.
Eggs: Bind the mixture and help the fritters set as they cook.
Butter: Adds richness and helps the surface brown on the griddle.
Milk: Loosens the mixture and adds moisture for a tender interior.
Flour: Thickens the batter and gives the fritters body and structure.

The step that matters

Cooking the spoonfuls on the griddle. The batter must be thin enough to spread slightly but thick enough to hold its shape. Medium‑high heat with a buttered surface lets the outside brown before the centre sets, so the fritter stays cohesive rather than sticking or burning.
