We are using both regular and horseradish mayo. I think you'll love the additional flavor that horseradish mayo brings to the table in this dip, but you can omit it altogether and just use all regular mayonnaise if desired.
Store homemade dill dip in an air-tight container kept in the refrigerator for up to 4 days. Be sure to refrigerate the dip when you are not consuming it.
Serve with fresh cut up vegetables, crackers, or potato chips.
