Combine all but the sliced scapes in a small saucepan over medium heat and bring to a simmer. Add the scapes and return to a simmer, then remove from heat and allow to steep for 20 minutes.
Pour everything into a clean half-pint jar, tightly seal it, and give it a good shake to make sure all the aromatics in the brine are well distributed. Refrigerate for at least 24 hours to allow the flavors to develop.
