Prep the caramelized onions. In a stovetop pan, add the oil and bring a medium heat. Add the onions and salt and cook until translucent. Cover the pan, keeping on low-medium heat, and cook the onions. Stir occasionally to prevent sticking, this is a low and slow process. Continue cooking until the onions are a golden brown color. Add the apple cider vinegar to deglaze the pan. The total cooking time should be 30-40 minutes. Remove from the heat and let cool completely.

In a food processor, add the sour cream, cream cheese, honey. Blend until smooth. Add about half the caramelized onions and blend. Stir in the other half of the onions. Salt to taste and adjust flavorings as desired.

Pour into a serving bowl and chill until ready to serve.
