Add the sour cream and mayonnaise to the food processor. Add in half the amount of lemon juice, honey, salt, and black pepper called for. Blend the salad dressing and then taste it. If it tastes too bitter, add more honey. If it doesn't taste bright enough, add more lemon juice, if it is too bland, add more salt and pepper. The amounts above reflect what I ended up using.
1/2 cup light sour cream, 1/2 cup light mayonnaise, 1 tablespoon lemon juice, 1 teaspoon honey, 1/2 - 1 teaspoon kosher salt, dash freshly ground black pepper
