Yes kids, its a microplane. Also known as a fancy grater or zester. One of my top 3 must have kitchen utensils. They are usually used for zesting citrus but I also like to use it on parmigiano or harder cheeses.
Now I am not a professional chef and I do try to set the oven on fire at least once a year... and yes one time succeeded and got to use a fire extinguisher but that is another story. I do have other graters but a microplane is smooth and easy to use. No muscle needed. Here I will demonstrate for you.
