To juice an onion, follow these steps in detail:

1. Choose a fresh onion:
Select a firm and healthy onion with no signs of softness or discoloration. The type of onion is up to your preference, whether it’s a white, yellow, or red onion.

2. Prepare the onion:
Peel off the outer layer of the onion and discard it. Cut off the root end and remove any excess roots attached to the onion. Rinse the onion thoroughly under running water to remove any dirt or debris.

3. Cut the onion:
Cut the onion into smaller, more manageable pieces so it fits into your juicer or blender. It’s recommended to cut the onion into quarters or eighths, depending on the size of the onion and the capacity of your appliance.

4. Extract the juice:
If using a juicer, feed the cut onion pieces through the juicer chute, following the manufacturer’s instructions. If using a blender, place the cut onion pieces into the blender jar and add a small amount of water or another liquid of your choice (such as lemon juice or vegetable broth) to ease the blending process. Blend on high speed until the onion is fully pureed and liquified.

5. Strain the juice:
Place a fine-mesh sieve or cheesecloth over a bowl to strain the onion juice. Pour the blended mixture into the sieve or cheesecloth, allowing the juice to separate from the pulp. Press the pulp with the back of a spoon or a spatula to extract as much juice as possible. Discard the remaining pulp or save it for other culinary uses.

6. Transfer and store the juice:
Once strained, pour the onion juice into a clean glass jar or bottle with a tight-fitting lid. Store it in the refrigerator for up to 3-4 days for optimum freshness. Remember, the strong smell and taste of raw onion juice may not be appealing to everyone, so consider adding it to other juices or recipes to mask its potent flavor. Additionally, consult with a healthcare professional before incorporating raw onion juice into your diet, especially if you have any underlying health conditions.
