Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries and softens the aromatics, adding richness to the liquid.
- Onions
- Release sweetness and savory depth as they cook and color.
- Carrots
- Add natural sweetness and body to the simmered liquid.
- Vinegar
- Adds acidity that brightens the marinade and helps draw out flavor.
The step that matters
Stirring until the vegetables begin to color. Browning the onions and carrots builds deeper flavor through caramelization, but scorching gives bitter notes that carry into the whole marinade. Keep the heat gentle and stir often.
