Instructions
Finely grate the truffle over the salt. I used a microplane to do this.
Mix with a spoon to combine, and ensure the truffle is evenly distributed throughout the salt.
Place the truffle salt on a silicone dehydrator sheet and spread it out so it's nice and flat.
Dehydrate at 100°F/38°C overnight (or for 8 hours).
Store in an airtight glass jar in a cool, dark place.

Notes
Drying out the mix is necessary because the truffle is quite moist once grated. If you don't have a dehydrator, this recipe can be made in the oven. Ensuring it stays on a low temperature is essential though. Anything over 104°F/40°C could slightly cook the truffle and reduce its pungency.
