Why it works: Parsley and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,563 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Poached Eggs
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Poach the eggs
Fill a saucepan with water and add salt and vinegar.
Bring the water to a gentle simmer.
Crack the eggs into the water and poach for 3-4 minutes until the whites are set.
Serve
Remove the eggs with a slotted spoon and place them on fried bread.
Top with melted butter and herbs or your choice of sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into soft, tender whites around a runny yolk when poached in water.
- Vinegar
- Helps the egg whites coagulate quickly, keeping them compact in the water.
- Melted butter
- Adds richness and moisture over the eggs and fried bread.
The step that matters
Poaching the eggs for 3-4 minutes. The water should be at a gentle simmer, not a rolling boil, so the whites set evenly without tearing. Timing matters because overcooking firms the yolk, while undercooking leaves the whites runny.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (egg, vinegar, bread, butter, parsley, anchovy, tomato):
- Capersfits about as well
- Tarragonthe original
- Thymefits about as well
- Garlicfits about as well
Fit is the average pairing score against egg, vinegar, bread, butter, parsley, anchovy, tomato. Candidates are from the same food group and used in at least 100 recipes.
