MAKE THE CANDY MIXTURE: In a large saucepan, stir together 2 cups sugar, 1 ⅓ cups applesauce, 2 packages of strawberry jello and 2 envelopes of unflavored gelatin.
Let this mixture stand for 1 minute.
Over medium heat, bring the mixture to a boil stirring constantly. Boil the mixture for one minute and then remove from heat.
Immediately pour the mixture into a greased 11x7 or 9x13 pan.
Repeat these steps with another 2 cups of sugar, 1 ⅓ cups sugar, 2 envelopes unflavored gelatin and 2 packages of cherry jello.
CHILL THE CANDY MIXTURE: Place both pans into the fridge for 3 hours.
CUT OUT THE HEARTS, DRY THEM: I find it is easier to cut the mixture into squares and use a metal spatula to pull the squares out and transfer onto a wax or parchment paper. This will be a sticky job but they will come out of the pan. (These are really sticky and if will feel like you are going to rip it pulling it out of the pan but just keep sliding the metal spatula under them and they will come out.)
Using a mini heart cookie cutter, cut out as many hearts as possible and place them onto a parchment or wax paper lined tray.
Let the candies dry at room temperature 8 hours or overnight.
COAT THE GUMMY CANDIES: After a minimum of 8 hours dry time take the remaining 1 cup of sugar and mix with the citric acid and dip each gumdrop candy in, coating it all around with sugar.
