Why it works: Chayote and flour share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and 12 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Cook the chayotes
Bring 4 quarts of salted water to a boil in a large saucepan.
Add the chayotes, cover, and cook until tender when pierced with a skewer, about 30 minutes.
Make the cream sauce
While the chayotes are cooking, whisk together the flour and ½ cup of skim milk in a small bowl until smooth.
In a large non‑aluminum saucepan, stir together the remaining skim milk and the evaporated skim milk.
Bring the mixture to a simmer over medium heat.
Very gradually whisk in the flour mixture.
Stir until the sauce boils and thickens.
Reduce the heat to very low and cook for 2 minutes, stirring occasionally.
Stir in the sour cream, parsley, and scallions, and season to taste with salt (optional) and plenty of pepper.
Serve
Drain the chayotes and cut into ¼‑inch thick slices.
Put the sliced chayotes in a serving bowl, pour the sauce over, and serve immediately.

Flour and milk share little aroma chemistry, yet 76,993 recipes mention both: they likely 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
- Chayotes
- Form the main body of the dish and carry the sauce, staying tender when cooked through.
- Flour
- Thickens the milk mixture into a smooth sauce as it heats and boils.
- Skim milk
- Forms the liquid base of the sauce, providing body without added fat.
- Evaporated skim milk
- Adds concentrated milk solids for a richer, creamier sauce texture.
- Low fat sour cream
- Adds tang and creaminess to the sauce when stirred in off the heat.
The step that matters
Adding the flour mixture to the milk. Flour clumps if dumped in at once. Whisking the flour into a smooth slurry and adding it very gradually to simmering milk keeps the sauce lump-free as it thickens.

Fit is the average pairing score against chayote, flour, milk, cream, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
