Peel, seed and slice cucumbers.
Cut onions to thin slices and mix with cucumbers.
Mix sugar and vinegar together until sugar is dissolved.
Add salt, pepper, garlic and dill to the vinegar and sugar mixture.
Pour the mixture over the cucumbers and onions and add the water.
Coat all the cucumbers and onions with vinegar mixture.
Refrigerate for 3-4 hours or overnight.
Chef's notes: The vinegar should at least cover ¾ of the cucumbers, so you may need to add more vinegar. If you do add more vinegar, be sure to adjust the sugar as well. Original recipe credited to Della Garretson Hover.
