I always loved cucumbers and onions growing up and made them for my family. My daughter didn't like it as well, complaining it's too sour so I used a recipe from my aunt from the south that would sweeten it up. I can say I now make this version most of the time, it's so fresh and delicious in the summer when we use our own garden veggies but it's still good with store bought veggies too. Enjoy!
Mix mayo, sour cream, vinegar, sugar, garlic, onion, & dill weed in a medium bowl.
Peel and slice cucumbers and onions and put in a strainer. Pour salt over the cucumbers and mix until well coated. Allow to sit for 1/2 an hour or so. Rinse salt off and pat cucumbers dry with a paper towel. This process brings the moisture out of the cucumbers so the recipe stays creamy instead of liquidy.
Stir cucumbers into mayo mixture and refrigerate for at least 2 hours. It will even taste better the next day just as the old fashioned cucumbers and onions would!
