Take the water and 2 cups hard cider and put in a pot with the sugar. Add the gelatin and let proof for a few minutes. Once swelled or bloomed, put the pot over medium heat and bring to a slow boil until the gelatin is dissolved.

Take off the heat and add in the remaining 2 cups of hard cider. Pour into a square baking dish and cover in the fridge for a few hours until set.

Once set, cut into small cubes and put in a 9x9 square dish, piling them on top of each other.

Mix 1/2 cups cold water and 2 gelatin packets together and let proof. Add in 1 1/2 cups boiling water and mix until gelatin is dissolved. Mix in one can of sweetened condensed milk. Let the mixture come to room temperature and pour 1 cup over the cubed cider Jello. Cover and let set in fridge. You can use the remaining amount to make sweetened condensed milk Jello as well.
