Directions

Prepare the jelly so it is cold and just about to set.
To make a tartar sauce, mix the jelly with vinegar and water until smooth.
For a thinner consistency, add more vinegar or water, or use milk or cream.
For a richer flavor, substitute water with cold chicken broth or unseasoned soup stock.
Serve the sauce cold with vegetables, meat, or fish.
