Add water with salt in a medium size pot. Bring it to a boil. Turn the heat off. Pour the boiling water over the cucumbers in a bowl. Keep the cucumbers submerged by weighing them down with a bowl or plate. Let it sit.
Drain the cucumbers. Holding the top end of the cucumber on the cutting board, run a small knife through the middle lengthwise. Turn the cucumber and make another cut through the middle lengthwise to make a cross cut.
Gently open each slit and insert about a teaspoonful or two of the stuffing. Repeat until all the cucumbers are stuffed. Place them in a jar or an airtight container. Leave it out at room temperature for a day. Then, store in the fridge.
