Add all of the ingredients into a blender. Blend until it forms what looks like a wet dough. It should be clumping onto itself.

Taste and see if you want to make it saltier.

Transfer into a small rectangle container. I lightly sprayed mine with oil just to prevent any sticking. Use a spatula to create a triangle (or you can make it a square).

Freeze for at least 1 hour before using. Then grate anywhere you like. Store in the freezer.
