I received it as a grated sample. I smushed it together into a smallish puck and tried to use it that way, but it keeps breaking apart and I have to reform it almost every day.
This is the 3rd grated sample I have tried and I guess I'm just not cut out to use them. None of them have worked well for me. Just broken and fallen apart each time.
Have you used a little water when pressing the sample into your mug/bowl/container? I have had pretty good luck adding a little water while reforming and then allowing the new puck to dry for a few days before lathering.
