Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries the aromatics and helps the ham and shallots brown in the pan.
- Lean raw ham
- Adds savoury, meaty depth that browns during frying and flavours the stock.
- Tomatoes
- Provide the main body and acidic tomato flavour, thickening as they reduce.
- Rich stock
- Supplies the liquid base that the tomatoes break down into and reduces to a thick soup.
The step that matters
Fry until the mixture colors. Browning the shallots and ham builds deeper, roasted flavour through the Maillard reaction. Pale frying gives a flatter soup, while over-browning can turn it bitter.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (butter, shallot, clove, thyme, ham, tomato, mushroom):

- Parsleybetter flavor fit
- Tarragonbetter flavor fit
- Macethe original
Fit is the average pairing score against butter, shallot, clove, thyme, ham, tomato, mushroom. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
