See, I had always had onion dip that came from a packet, or some store-bought version, and I was never a bit fan. It was just too… oniony. Too processed. And then a friend brought a homemade version to our house one day and I totally changed my tune. This is sweet and fresh. I couldn’t stop eating it.

An added bonus is that this dip is definitely a recipe to make ahead. The longer it sits, the longer the flavors infuse into the sour cream and mayo. Serve with veggies, crackers, or chips.
