Notes

TARRAGON: You can easily substitute dried tarragon. Use 2 teaspoons dried tarragon in place of the fresh version.
Add the dried tarragon at the beginning of cooking (with the other seasonings) so it has time to release its flavor into the sauce. Dried herbs are more concentrated, so a smaller amount gives the same flavor. If using fresh tarragon, wait to add it until the end to keep its bright, slightly anise like taste.
Tarragon adds a subtle sweetness and depth to this dish, but if you need a substitute, you can use half parsley and half basil for a milder flavor profile.
