In a medium saucepan, over low heat, add 1/2 c (120ml) water and 2 Tbsp (10g) agar powder. Whisk quickly. Cover pot and let sit undisturbed for 3 minutes.
While that is cooking, in a small bowl, dissolve 2 Tbsp (16g) tapioca starch in 2 Tbsp (15ml) water.
While whisking continuously, add the cheese mixture to the agar mixture and whisk for 3 more minutes.
While continuing to whisk, add the tapioca solution to the cheese mixture. After adding this, the mixture will thicken considerably and start to stretch like melted cheese.
You could serve it as is in a saucy dish, but if you'd like solid cheese, pour the mixture into a mold and put in the fridge overnight.
Cut the cheese into 12 servings. You can slice it, serve it cold, shred it, or melt it!
