Please a steaming basket in a large saucepan filled ⅓ with water.
Preheat the saucepan on medium heat while you make your conkies.
In a large bowl, add all of the ingredients - pumpkin, sweet potato, coconut, raw cane sugar, allspice, cinnamon, nutmeg, pink salt, vegan butter, coconut milk, vanilla essence, mixed essence and cornflour.
Mix everything together to make a smooth paste consistency.
Add the coconut milk if needed, but don't add too much as you need the mixture to be on the thicker side.
Do a taste test of the mixture in case you want to add any additional sugar.
Once the mixture is ready, set it aside.
Cut the banana leaves into 8x8 inches or use 8x8inches of parchment paper and 10x 10 inches of aluminium foil (if you don't have banana leaves). You will need roughly 20 banana leaves or 20 parchment paper and aluminium foil (each) (if you are using that method) and then set aside.
Place the banana leaves in a large bowl with boiling water (must be boiling) and completely saturate for a few minutes.
Then drain off the water and blot the leaves dry.
Microwave the banana leaves for up to one minute (this will soften them).
For the banana leaf method - place the banana leaf on a clean flat surface.
Add a few tablespoons (up to 3) of the mixture in the centre of the leaf, being careful not to overfill.
Use the banana leaf to fold one side vertically towards the centre. Then fold the other half towards the centre. Then fold upwards and then finally downwards, it should look like a parcel.
Place some twine underneath the banana leaf and tie it to secure the top and bottom folds, so it doesn't open and repeat the above steps with the rest of the mixture.
For the aluminium foil method - place the aluminium foil with the parchment paper directly on top of a clean flat surface.
Add a few tablespoons (up to 3) of the mixture in the centre of the parchment paper, being careful not to overfill.
Use the foil to fold one side of the parchment paper vertically towards the centre. Then fold the other half towards the centre. Now follow on by folding in both sides of the foil, then fold upwards twice and then finally downwards twice, it should look like a sealed parcel.
Repeat the above steps with the rest of the mixture.
Carefully add the wrapped parcels onto the steaming basket (you may need to do this in batches depending on the amount/size of the steaming basket).
Cover the saucepan with the lid on medium heat.
Steam the parcels for up to an hour (until they are tender) (you can test the readiness around 45-50 minutes by carefully unwrapping the parcel to see if they are ready).
Once steamed, allow to cool down before serving them.
