How to make
Wash the cornichons well. Dissolve the salt in 3 liters of water and pour it over the cornichons.
Leave them for 12 hours, then strain and rinse them. Arrange the cornichons, peeled onions and dill tightly in a wide clay pot.
Boil the water, sugar and vinegar and as soon as you remove the mixture from the heat, add the aspirin. Pour the hot brine over the cornichons.
Close the opening of the container with cellophane and put a cotton cloth on it. Store in a cool and dark place. The pickles are ready to eat after 6 weeks.
