- Toss cucumbers and onions in a bowl with salt.
- Take a second bowl, fill with ice, and place over the cucumbers and onion and let it stand for 6−12 hours.
- For brine, combine the rest of the ingredients, bring to a boil, and pour directly over cucumber and onion.
- Allow to cool slightly and place in refrigerator for at least one day (and up to two weeks).
- Use as garnish on fried oysters with deviled egg sauce…or just keep on hand for snacking!
