Anna's Marinated Cucumbers This is a sweet and sour side-dish created by Anna's dad, Tim Mitchell. 1 large cucumber, peeled and sliced thin. 1/2 Large red onion, sliced thin. Salt White vinegar Sugar to taste Combine cucumber and onion in a large bowl. Stir in a generaous amount of salt. Let sit for 30 minutes. (The salt will leach water out of the cucumber to help dilute the acid in the vinegar) Add enough vinegar to half-cover the vegetables. Add sugar, a little at a time until it suits your taste. It should be a sweet and sour flavor. Cover the bowl with plastic wrap and refrigerate at least an hour until serving.
