Substitutions / adjustments
Originally this recipe called for A-1 Steak Sauce. That isn't something I often have on hand so years ago I switched to Worcestershire sauce. Either one works great. If using A-1 Steak Sauce, you will need about 1 1 /2 tablespoons of it.
If you want a thicker dip or more of a spread, omit the sour cream and add a total of 16 ounces of cream cheese.
I like using celery seeds, but you can easily use finely chopped fresh celery. It also adds a nice crunch to the dip.
