Why it works: Shallot and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 602 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Poached Eggs, Portuguese Style
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the tomatoes
Preheat the oven to 350°F (175°C).
Cut the tomatoes in half crossways and remove the seeds.
Place the tomato halves in a buttered sauté pan and bake for a few minutes to set.
Make the stuffing
In a skillet, fry the minced shallots in butter until soft.
Add the bread crumbs, parsley, tarragon, and chopped beef marrow to the skillet.
Bind the mixture with the egg yolk and season with salt, pepper, and nutmeg.
Stuff, bake and serve
Stuff the tomatoes with the mixture and return them to the oven to brown.
Toast the bread slices and place each stuffed tomato on a slice.
Poach the eggs, place one on top of each stuffed tomato, garnish with parsley, and serve on a folded napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Poached eggs provide a rich, set topping that adds creamy texture and substance to the dish.
- Tomatoes
- Hollowed halves hold the stuffing and add moisture and acidity as they bake.
- Bread crumbs
- Absorb moisture from the stuffing and help it hold together in the tomato halves.
- Egg yolk
- Binds the stuffing mixture so it holds its shape when baked.
- Shallots
- Softened in butter, they add mild sweetness and aromatic depth to the stuffing.
- Beef marrow
- Adds richness and fat to the stuffing, giving it a softer, savoury texture.
The step that matters
Poaching the eggs. Eggs cooked in water that is too hot or boiling can break apart and turn rubbery. Gentle simmering keeps the whites together and the yolks soft.
