In a small bowl, combine a quarter (roughly) of the butter as well as truffle paste or truffle oil (whichever you are using) and mix well to combine.
200 g unsalted butter, 1 teaspoon truffle paste or truffle oil
Place remaining butter in a larger bowl, then add truffle butter mixture and grated parmesan, mixing well to combine.
2 tablespoon freshly grated parmesan cheese
Add fresh black pepper and salt to taste.
fine salt and black pepper
Use immediately, or place onto parchment/baking paper and roll into a log and refrigerate.
Notes
Truffle paste or truffle oil will both work in this recipe - use whichever you can get your hands on.
Truffle flavour and intensity can vary greatly from one product to another. Start small with your truffle ingredients and work up from there.
I like to use unsalted butter as salted butter products can vary in their salt content, and add it myself to taste.
Use a fork or a simple traditional potato masher to mix the butter together.
You only want the butter to be slightly soft, just enough so that you can mix it. If it gets too soft the consistency of your butter will be different after it's refrigerated again.
