Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brussels sprouts
- The main vegetable; boiling softens their dense leaves until tender.
- Butter
- Fat that coats the sprouts, adding richness and carrying flavor.
- Parsley
- Adds fresh, green aroma and a bright color at the end.
The step that matters
Boil only until tender. Overcooked Brussels sprouts turn mushy and release stronger sulfur compounds, which give a bitter, cabbage-like smell and taste. Stop boiling once a knife slides in easily.
