Input: [header] How to extract juice from an onion [title] Peel the skin. [step] Use a sharp serrated knife to cut a small slice, no larger than 1/2 inch (1.27 centimeters), from the root end of the onion. Slice through the onion until you reach the skin on the other side, but do not cut through the skin. <sep> (A) Grab the partially cut end and pull it down, past the length of the onion, to draw back a portion of the skin. Grab the remaining skin with your thumb and first two fingers and draw it back to remove it. (B) Cut along the edge of the onion with a paring knife to slice it down the middle. [substeps] Removing the skin does not completely remove the core, but rather makes it easier to extract. (C) [substeps] If the skin is peeled off, do not cut through it, but break it. [title] Slice the skin away from the onion. (D) [substeps] Avoid sharp pruning shears. Serrated blades can damage the onion and waste the juice.
Output:
A
