I love artichokes and spinach, I'm just not a fan of them together. I also don't like adding mayonnaise to anything unless it's absolutely necessary. I don't think this recipe needs it because of using canned artichokes, and sour cream, plus this entire recipe is placed in a food processor to which it is almost a pureed consistency. I feel that spinach takes away from the artichokes flavor, consistency and texture. Most of us make these types of recipes for parties, potlucks & get-togethers, who wants spinach stuck in their teeth all night! :D Thanks for the recipe Brandy B.
