There are lots of pasta salad recipes here but I don't see this particular variation. I love dill in most anything and combined with cucumbers and pasta, it's tart/creamy comfort food to me. For even more color & crunch, radishes could be added for another twist. You may need to adjust the mayo and sour cream amounts - I don't really measure it so I've guessed. I start with a large dollop of each then add till I get the texture and taste that I want. Update: Thanks to the first reviewer for finding my typo with the salt; it has been corrected.
