This has been discussed in at least two threads, here and now here. Some claim it works, others don't agree, some claim potatoes don't even absorb salt. Into a 2 qt. pan I measured 1 Liter (1 Kilo) of tap water. In that, I dissolved 118 grams of canning salt. Why 118 grams/liter? It's a solution I often use for pickling and knew it's specific gravity using my hydrometer. Water weight = 1000g Pot weight = 534g Salt weight = 118g Total = 1652g Potato weight= 446g Total = 2098g Hydrometer read
