Weigh out and distribute beetroot juice, balsamic vinegar, Xanthan Gum, salt, and Calcium Lactate in separate bowls.

Pour everything into a tall bowl and blend with an immersion blender.

Place the silicone mold on a tray (for easy transfer to the freezer).
Fill all the cavities and let the mold sit for about 30 minutes to avoid air bubbles in the liquid.

Place the mold in the freezer until the liquid is completely frozen. Preferably do this the day before!

Put the cheese in a bag and place it in the freezer.
About 30 minutes before you want to make the spheres, blend Sodium Alginate and water with an immersion blender. After the 30 minutes, the bubbles should have dissipated.
Time to work some magic!
Place the bowl of Sodium Alginate and a bowl of water next to each other, find your slotted spoon, and take the silicone mold out of the freezer.
Carefully remove the frozen spheres from the mold.
Place them in the Sodium Alginate solution, but not too many at a time. They must not touch each other!
Use the slotted spoon to gently stir the solution and turn the spheres a few times so they come into contact with the solution all around. This is where the Calcium Lactate and Sodium Alginate react with each other, giving the spheres their form.
Now use the slotted spoon to scoop up the spheres and place them in the water. Gently stir the water, so the spheres become completely 'clean'.
Take the cheese out of the freezer and grate it. If you're using a mandolin, you can cut beautiful flakes.
Place the spheres on spoons and garnish with cheese flakes and rosemary leaves.
