Truffle butter is a seasonal specialty that is one of many wonderful ways you can preserve a little of your truffle for months to come. Recipe video is above!
Soften the butter by leaving it to sit in a bowl on the bench for 30 minutes to an hour. The time needed will really depend on the weather at the time you're making this.
Add the salt, then grate the truffle straight over the top.
Mix well to ensure the truffle is evenly distributed throughout the butter.
Put the butter back in the fridge for 45 mins to an hour to firm up slightly. This will make it much easier to shape back into a block or a log. If you're keeping it pressed in a small dish you can do this straight away then place in the fridge.
If shaping into a block or log - remove the butter from the fridge and shape as you wish. I used butter pats to shape mine back into a block. You can also roll it into a log in baking paper and store it that way.
Store in the fridge. This will keep its lovely truffle flavour for a good couple of months.
Notes
I have specified using unsalted butter here however, if you'd like to use salted butter just leave out the salt in the recipe.
