Cucumber and Onion Salad

I got this recipe from my mom at some point, but we didn't start making it until this summer.  Not much of a kid pleaser, but Greg and I love it!

2 English cukes, about 1 ft. long
1 onion, cut into fourths and thinly sliced
Salt
Pepper
White sugar
Rice vinegar
Pickle juice
Sour cream
1 tsp dried dill
1/2 cup ranch

On the bottom of the dish with an airtight lid, make a single layer of cucumber slices.  Sprinkle them with salt and pepper.  Scatter a layer of onion on top, and sprinkle with sugar.  Repeat until cuke and onion are used up.  Add a small amount of rice vinegar and pickle juice.  Put the lid on and shake well to distribute the juices.  Drain liquid.  In a separate bowl, mix about four spoonfuls of sour cream, dill, and ranch.  Add to cucumber mixture.  Stir until well mixed.  Cover and chill to blend flavors.
