In a separate bowl whisk together the vinegar, salt, and sugar until well combined.
Place pickling solution in a vacuum chamber bag, along with the cucumbers and bean sprouts. Place bag in vacuum chamber and run a vacuum cycle. Once the cycle is complete, you can enjoy the pickles immediately or refrigerate them sealed for up to 24 hours.
If You Don't Own a Vacuum Chamber
Instead of placing the pickling solution in a vacuum chamber bag, leave it in the bowl. Add the cucumbers and beansprouts to the bowl and let pickle overnight in the fridge.
