Why it works: Cauliflower and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 687 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
French Pickle
Ingredients
Directions
Prepare the vegetables
Combine the chopped tomatoes, onions, celery, and cauliflower in a large pot.
Make the pickle
Add vinegar, brown sugar, mustard, salt, red pepper, and turmeric to the pot.
Heat the mixture until it is scalding, but do not let it boil.
In a separate bowl, beat the raw egg and mix in the flour and butter.
Stir the egg mixture into the pot and mix well.
Immediately seal the mixture in Perfect Seal Jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Supply the bulk of the chopped vegetables and tart, fresh flavor.
- Vinegar
- Provides the acidity that preserves the pickle and gives it its sharp taste.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Egg
- Thickens the mixture as it cooks, giving it a richer, more body-filled texture.
- Flour
- Helps thicken the sauce together with the egg for a smoother consistency.
- Butter
- Adds fat for richness and a smoother mouthfeel in the thickened sauce.
The step that matters
Adding the egg mixture. The raw egg must be stirred into the hot mixture gradually and well so it thickens smoothly without scrambling. Keeping the pot from boiling protects the egg's texture and the sauce's consistency.
