How to make
Heat water in a deep pot.
When the water starts to boil, add 1 tablespoon of salt.
Put the peeled sweet potato in it and leave them to simmer.
The degree of readiness can be checked by piercing a potato with a fork. It takes about 30 minutes.
Take out the potato and put it in a separate bowl. Add the butter and mash well with a fork.
Then add the milk and mash the mashed potatoes, but make sure not to make the texture too thin.
The sweet potato puree is ready!
