Describe the request
Make sure to include:

1. What problem or issue would this enhancement solve?
   Preserving food by pickling requires saltwater, but this can only be obtained from the ocean and only one barrel can be carried at a time.
2. Describe the feature itself - what would change, what would happen. In general more detail is good!
   A new recipe to create saltwater from fresh water and salt makes food preservation more accessible for homes far from the sea.
