Every week, baking expertAlice Medrichwill be going rogue on Food52 -- with shortcuts, hacks, and game-changing recipes.Today: Your comments shouldbe pithy; your citrus should not. Here's how to achieve perfect citrus segments and leave all of the pith and membrane behind.Are knife skills on your list of New Years resolutions' Segmenting citrus is one of the most satisfying (and fun) things you can do with a sharp knife! The results are gorgeous, delicious, and surprisingly impressive to others. Use a straight rather than serrated blade. I like a chefs knife, but even a 6-inch knife will do, so long as the blade is very sharp. Practice makes perfect. Your fourth orange will be better than your first.Follow my lead:Wash the orange rinds. Cut a generous slice from each end of one orange to expose a round of bare fruit about 1 1/2 inches in diameter. Set the fruit on one cut end on a cutting board. Starting at the top edge of the rind, follow the contour of the fruit as you cut downward with a very short sawing stroke to remove a wide strip of rind, pith, and membrane. Continue around the fruit, removing as much membrane as possible without wasting too much fruit. When you are done, inspect the fruit and trim any remaining membrane. (Tip: If you left a lot of membrane on the end of the fruit closest to the cutting board, remember to follow the curve of the fruit with the knife when you cut the next orange.) Repeat with the remaining oranges.The next step is cutting and removing the segments. You can hold the orange in a cupped hand over a bowl as you work, letting the juices and sections drop into the bowl. Or, if you are not comfortable cutting with the fruit in your hand, place the fruit on the cutting board with one side facing up.To segment, cut into the fruit right next to a membrane. When the blade reaches the center of the orange, rotate it to peel the segment away from the opposite membrane. Or, simply cut both sides of the segment away from the membrane -- whichever method is easier for you.Repeat to remove all of the segments. You'll be left with themembrane attached to the orange like the open leaves of a book.Save any juice on the cutting board and squeeze extra juice from the membranes and the ends of the orange rinds.Secret sharp knife tip: If your knives are not as sharp as they should be, try one you rarely use (my boning knife is always sharp because I dont use it much!) or use the part of your chefs knife blade that is closest to the handle -- it will probably be sharper than the rest of the blade!More: Watch Amanda and Merrill show off their segmenting skills.Photos by Bobbi LinFood52 is a community for people who love food and cooking.
