This is a basic Tartar Sauce.  Modify / substitute the ingredients for your taste.

1 part Kefir Cheese (one brand is The Greek Gods) or sour cream
1 part Mayo (I usually use the brand made with Canola Oil and eggs)
Juice from half of a lemon
1 finely diced shallot (~2 tblsp)
1-2 tblsp diced pickles, pickle relish, or capers.
1 dice chile pepper (seeds removed) - jalapeno, Serrano, habanero, pablano, . (optional)
Salt to taste - usually not necessary.

Options:
Add 1-2 tblsp diced celery
Add 1-2 tblsp diced bell pepper (red, yellow, orange and/or green)
Add 1 tsp diced chives
Add 1 or more tsp Sriracha sauce
Substitute Lime juice for Lemon juice
Add 1 tsp mined Lemon zest and reduce lemon juice
Haven't tried but maybe Worcestershire sauce or Liquid smoke by be interesting.
