You can also make your own tartar sauce.

I like homemade the best.

I use Mayonaise (you can either make this, there are recipes on the board, with eggs and oil) or you can buy Hellman's real mayonaise, or Kraft Mayonaise, both low in carbs. Mix the mayo with a bit of Dijon mustard or regular mustard (to taste) and add dill pickle relish. I prefer dill pickle relish to sweet pickle relish, plus no carbs. This is the best tartar sauce and you can make it just when you need it and it does not go to waste.

Good luck.
