Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Moulded Spinach
Ingredients
Directions
Prepare the spinach
Pick over and wash the spinach.
Cook the spinach in a large pot of boiling salted water with baking soda and sugar until tender.
Drain the spinach thoroughly and finely chop it.
Season the spinach with butter and salt, then reheat.
Mould and serve
Press the spinach into a buttered border mold and keep it warm until serving.
Transfer the mould to a hot platter and fill the center with seasoned small boiled beets.
Surround the mould with hard‑boiled eggs cut into sixths lengthwise.
Serve the dish with oil and vinegar if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the main body of the mould, giving bulk and a soft, tender texture once cooked and chopped.
- Baking soda
- Raises the water's alkalinity during cooking, which helps the spinach keep a bright green color.
- Butter
- Adds fat and richness, carrying flavor and smoothing the texture of the chopped spinach.
- Hard-boiled eggs
- Add protein-based richness and a firm, contrasting texture around the soft spinach mould.
The step that matters
Drain the spinach thoroughly and finely chop it. Cooked spinach holds a lot of water. If it stays wet, the mould will be loose and watery and may not hold its shape when turned out.
