Why it works: Sage and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Forcemeat Onions
Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Peel the onions and scoop out the insides.
Mince the raw liver with sage leaves, small onion, pepper, salt, batter, and bread crumbs.
Fill the hollowed onions with the forcemeat mixture.
Roast
Roast the stuffed onions in a 350°F (175°C) oven until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Hollowed shells that soften and turn sweet as they roast, holding the filling.
- Liver
- Forms the body of the forcemeat, and its proteins set into a firm filling when cooked.
- Bread crumbs
- Absorb juices from the liver and onion, helping the forcemeat hold together.
- Sage
- Adds a savory, herbal aroma that balances the rich liver.
The step that matters
Roast until cooked through. Raw liver must reach full doneness so its proteins set and the filling is safe to eat. The onion can look tender before the center of the filling is fully cooked, so check the filling itself.
Swap the onion
How well each one fits the dish's main ingredients (liver, sage, pepper, bread):

Fit is the average pairing score against liver, sage, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
