Ingredients
Directions
Infuse
Combine the fresh tarragon, basil, bay leaves, shallots, and nasturtium in a large container.

Seal the container and let it sit for 2-3 weeks in a cool, dark place.
Strain and use
Strain the vinegar through a fine mesh to remove the herbs before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh tarragon
- Its aromatic oils infuse into the vinegar, giving it the main tarragon flavour.
- Vinegar
- Acts as the solvent that draws aroma from the herbs and adds sharp acidity.
- Basil
- Adds a sweet, aromatic herbal note that blends with the tarragon.
- Bay leaves
- Release a subtle resinous aroma slowly into the vinegar over the steeping time.
The step that matters
Fully submerge the herbs. Herbs left above the liquid are exposed to air and can spoil or grow mould, while submerged herbs stay protected and infuse evenly.
Swap the basil
How well each one fits the dish's main ingredients (tarragon, shallot, vinegar):
- Capersfits better
- Parsleyfits better
- Thymefits better
- Basilthe original
Fit is the average pairing score against tarragon, shallot, vinegar. Candidates are from the same food group and used in at least 100 recipes.
