First, find the base of the onion. That’s where all the roots were.
#2 Before Peeling, Do This
Taking your small knife, figure out a rough circle around the base. You want to leave a thin circle of onion between the root and you knife’s circle.
#3 Cut A Cone Out Of The Onion
Insert the knife on an angle, cutting a cone out of the onion. You should be inserting the paring knife around 1/3 of the way into the onion.
#4 Lift Out The Cone
Now you should be able to lift out the cone. This part of the onion is where the gas that makes you cry come from. After you have removed this part of the onion, you are free to cut up the rest of the onion in any way you like, with zero risk of tears!
