DAY 2 and 3 - Repeat the day one process by pouring off the salt water and recovering with fresh salt water.
DAY 4 - Pour off water. Cover cucumbers with fresh boiling water with alum (2 1/2 tablespoons alum to 1 gallon water).
DAY 5 and 6 - Repeat the Day four process by pouring off the alum water and recovering with fresh alum water.
DAY 7 - Pour off water. Cover with equal parts cider vinegar and water. This mixture should be boiling.
DAY 8 - Pour off vinegar solution. Pack cucumbers in jars and fill with equal parts cider vinegar and sugar. Add 1 tablespoon pickling spices and 1 extra tablespoon sugar in each jar before sealing.
* Alum = aluminum potassium sulfate = ammonium aluminum sulphate = potassium aluminum phosphate. Alum can be found in most grocery stores by the spices.
