Why it works: Potato and dill work together. They rank in the top 3% of all ingredient pairs, and cooks put them together in 423 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Zucchini and Potato Dish
Ingredients
Directions
Prepare the vegetables
Clean the zucchini, cut into pencil-thick slices, salt and let sit for 10-15 minutes. Wipe with a cloth, dredge with flour and fry in lard.
Peel the potatoes, slice thinly and fry in lard.
Layer and bake
In a pot, place a layer of potatoes, one of zucchini, and then sprinkle with dill.
Then another layer of potatoes, one of zucchini, and again another potato layer.
Pour the sour cream and salt.
Bake and when the dish is almost done, add a tablespoon of butter, spreading it onto the whole surface.
Serve
Serve hot with a little chopped dill on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Zucchini (in the method)
- Forms the main vegetable layers and adds moisture and mild sweetness as it cooks.
- Potatoes
- Form the starchy layers that soften and hold the gratin together.
- Sour cream
- Adds richness and moisture that coats the layers and turns creamy as it bakes.
- Flour
- Light dusting on the zucchini helps it brown in the fat and gives a slightly thickened coating.
- Lard
- Fat used for frying that adds flavour and helps the vegetables brown.
- Butter
- Melts over the top near the end, adding richness and gloss to the surface.
The step that matters
Salting and drying the zucchini. Salt draws water out of the zucchini. Wiping it dry before dredging and frying helps it brown rather than steam, and keeps the gratin from becoming watery.
Swap the dill
How well each one fits the dish's main ingredients (potato, butter, cream, flour):
- Nutmegfits better
- Capersfits better
- Parsleyfits better
- Dillthe original
Fit is the average pairing score against potato, butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
