Why it works: Clove and ginger match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,038 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Walnut Ketchup
Ingredients
Directions
Make the ketchup
Press out the juice from the young walnuts and let it simmer.
Skim the juice well, then add anchovies, shallots, cloves, ginger, mace, pepper, and garlic.
Simmer the mixture until the shallots sink.
Pour the mixture into a pan and let it cool.
Bottle and age
Bottle the ketchup, dividing the spices evenly.
Cork tightly and tie down with a bladder.
Let it age for at least one year before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young walnuts juice
- Forms the liquid base that carries all the other flavours.
- Anchovies
- Adds deep savoury umami flavour that rounds out the sauce.
- Shallots
- Contribute aromatic flavour and body as they soften during simmering.
- Cloves
- Add warm, pungent aroma that persists through long ageing.
- Ginger
- Adds sharp, warm aromatic notes to the sauce.
The step that matters
Skimming the juice before adding the other ingredients. Skimming removes foam and impurities that rise during simmering. Leaving them in can cloud the liquid and give it off flavours, and a clearer base keeps the finished ketchup clean-tasting over its long ageing.
