Bring the creamer and soymilk to a boil...but watch it! Both times I made this I looked away for a second and it completely boiled over the saucepan and made a huge waste! It gets very big and bubbly if you don't stir!
Once boiling, remove from the heat briefly to add the agar powder, rice vinegar and smoked salt.
Mix the tapioca starch in a small cup or bowl with a few tablespoons of soymilk and set aside.
Put mixture back on the heat, bring to a boil again, then add the rest of the ingredients, including the tapioca mixture, stirring as you go.
Cook for 10 or so minutes, make sure it comes to a boil at least once, then remove from heat and pour in a Tupperware or other container to set.
After it cools a bit you can store it in the fridge. Mine lasted a bit over a week!
