Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Stewed Vegetable Marrow
Ingredients
Directions
Prepare
Peel the young Vegetable Marrows and cut them into pieces.
In a saucepan, melt the butter and add the marrows, seasoning with salt and pepper.
Cook for 15 minutes, tossing occasionally.
Stew and finish
Add stock to reach half the height of the marrows and boil gently until tender.
Remove from heat and stir in the beaten egg yolk mixed with lemon juice and parsley.
Serve the marrows over hot buttered toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young vegetable marrows
- Form the main body of the dish, softening into a tender stew as they cook.
- Butter
- Adds richness and fat, helping the marrow pieces soften and carry flavour.
- Egg yolk
- Thickens the warm cooking liquid into a smooth, creamy sauce when stirred in off the heat.
- Lemon juice
- Adds acidity that brightens the rich butter and egg sauce.
- Plain stock
- Provides cooking liquid that gently braises the marrow until tender.
The step that matters
Stirring in the egg yolk. Egg yolk thickens through gentle heat. Adding it to a boiling liquid or leaving it on the heat can scramble it, so remove the pan from heat first and stir steadily.
