As you can see in an older post, we visited Tetsuya's a little while back and the first thing we were given was some warm crusty bread and Tetsuya's signature truffle butter with parmesan. There's no other way to describe it than the best butter either one of us has ever tasted.
So I had the chance this weekend to bake some homemade bread (I'll post that later) for a lunch get-together at a mate's place and decided I wanted to recreate the truffle butter to bring along with me.
It's actually quite simple if you can get ahold of Tetsuya's Truffle Salsa. I was lucky enough to pick up a jar at The Essential Ingredient in Rozelle. The stuff isn't cheap - $22 - but it contains 80g of the salsa, which is enough to make two batches of the butter.
The other two things you need is 160g of really good unsalted butter and 25g of finely grated parmesan. Combine all the ingredients in a bowl, set into shape, cover with cling film, and then refrigerate until it's firm.
Trust me, do this one time in your life. The taste is mind-blowing and you will certainly impress your guests.
