Place all of the ingredients in a bowl or storage container. Stir well. Adjust the seasoning to taste and stir again. Store in the refrigerator, tightly sealed, for up to one week.
Notes
If your homemade tartar sauce is too thick, thin it with lemon or pickle juice. If it's too thin, stir in a bit more mayonnaise.
Always taste the sauce before serving and adjust the seasoning as needed. Sometimes a bit more of one ingredient can elevate the flavor.
Storage
Store the tartar sauce in an airtight container in the refrigerator for up to one week. Freezing is not recommended as it can affect the texture and consistency when thawed.
If your tartar sauce has been stored for a few days, give it a good stir before serving to recombine any separated ingredients.
