Fill a large stock pot or saucepan with water (about ¾ full), add ½ teaspoon of pink salt and then bring to the boil.
Meanwhile, fill a large bowl ¾ full with warm water and ½ teaspoon of pink salt and set aside.
Rub your hands with some olive oil or wear gloves before starting and then slice the top and the bottom of banana (don't slice if off completely).
Slice the peel lengthways (don't slice too deep, ¼inch should do).
Holding the green banana in one hand, use your thumbs to push the skin away until it is completely removed. Repeat this step with the rest of the banana.
Place the green banana in the bowl of warm water mixed with the pink salt, this will slow the oxidation process a little.
Use a grater, to grate each green banana using the side of the grater with the small holes over a medium sized bowl.
Place the pink salt in the same bowl as the grated banana.
Add the flour to the bowl slowly then start to knead, you will notice that the flour will start to come together with the green banana without adding water at first.
As you continue to knead, you may need to add some water, it shouldn't be a lot, add a little (about ¼ cup) at a time until you form a soft pliable dough (it shouldn't be too firm nor too sticky) add more flour or water 1tbsp at a time to get the right consistency.
At this point you can divide the dough into equal parts for better precision but I don't I just work freestyle, as that's how I was taught growing up.
Pinch off a small amount of dough, I usually pinch off about a golf ball size amount.
Roll it in the palm of your hands and then flatten and shape into a circle (about ½ inch thick).
Use your thumb to make a dip in the middle.
Repeat the above 3 steps with the rest of the dough.
Carefully lower each dumpling into the saucepan.
Boil (lower the heat to medium-heat if it is bubbling too much) for about 25 minutes (around the given time, you will notice the dumpling will float).
A few minutes into cooking the dumpling use a spoon to stir the dumpling, this will stop them from sticking at the bottom of the pot.
Once the dumpling has cooked, use a slotted spoon to remove them.
