Add the cheese, spirit of choice, olive brine, salt, pepper, and optional add-ins like lemon zest, garlic, olive oil, and thyme, to a small food processor or bowl.
Blend or mix until smooth and creamy, adding a little extra olive oil or spirit if needed.
Taste and adjust the seasoning, adding salt only if necessary.
Transfer to a piping bag and carefully fill each olive. Refrigerate until ready to serve.
