It's just mixing, blending and simmering. You can't go wrong! I used round ramekins as a mold to be able to slice tradicional round mozzarella slices.
My changes to the agar step:
I used more agar (3 TBS in total). Also let it simmer for 3 minutes before pouring into the blender; I find 1 minute too short for thickening.
