Classic tartar sauce

Ingredients:

• 3 egg yolks
• 1/4 cup apple cider vinegar 5%
• 1.5 cups of vegetable oil
• 2 shallots, finely chopped
• 3/4 cup finely chopped gherkins
• 1/2 cup whole grain mustard
• 1 teaspoon celery salt
• A pinch of cayenne pepper

Preparation:

1. In a food processor, combine the egg yolks and apple cider vinegar. With the processor running, gradually add the oil and process until emulsified. If the mixture begins to thicken too much, add the oil more quickly.
2. Add the remaining ingredients and taste. Season with salt if needed. Transfer the tartar sauce to a lidded container and refrigerate until ready to use.
