This is a deli counter translated into a cold party bowl. Equal measures of mayonnaise and sour cream make a pale, tangy base; four ounces of corned beef bring salt and chew; chopped onion and parsley keep it awake. Horseradish is the only dial, and the recipe wisely leaves it optional.
The queued card is concise enough to fit on an index card: combine, stir, serve with bagel pieces. That economy stays intact here. The extra detail is practical rather than transformative—how finely to chop, when to stop mixing, how to taste the heat through bread, and how to keep a dairy-and-deli dip properly cold through a gathering.
“Shari Stensrud described this as a potluck favorite: a creamy, lightly kicked-up dip made for dunking bite-size bagel pieces.”
Build the white base first
Whisk mayonnaise and sour cream smooth before the meat and herbs enter, then switch from whisking to folding.
Keep the beef in small pieces
Fine chopping distributes the deli flavor while leaving enough definition to read as corned beef, not tinted cream.
Taste through bread
Judge the optional horseradish with a plain bagel piece; the bread mutes heat more than a bare spoonful does.
