Every kitchen needs a microplane grater. This is a long grater which grates very finely, it's 12 inches long (30cm approx) and is useful for parmesan, chocolate and lemon/lime zest.
Every chef has at least one and every kitchen NEEDS one - that's why it's on my list. I searched high and low to get mine, so I have done all the hard work for you. Here it is and you need it.
