Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as it cooks and sets it into a smooth, creamy base.
- Butter
- Adds richness and a smooth texture to the cooked dressing.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Provides the acidity that gives the dressing its tang.
- Thick sweet cream
- Adds moisture and richness, softening the dressing once cooled.
- Apples
- Provide crisp texture and fresh, fruity flavor to the salad.
The step that matters
Stir in the beaten egg and cook until thickened. Egg proteins set as they heat, thickening the dressing. If the heat is too high or the mixture is not stirred, the egg can scramble into lumps, so keep the heat moderate and stir constantly.
