You will want to use several Aloe Vera leaves. You will hopefully be able to find them in the specialty produce section of a well stocked grocery store.
Avoid any damaged leaves or bruises where the gel has turned dark. I bought three of them and one was completely bruised with dark colored gel which I did not detect when I bought it. I recommend either picking up an extra leaf or if you do not have enough you can substitute with distilled water.
Wash and then trim the spiked edges off of the sides of the leaves.
Then lay the leaves flat and remove the skin on the top of the leaf, with a spoon you will remove the gel inside and place it into a blender. This part is pretty slimy.
Once all of the gel is in the blender, pulse a few times and then blend for about fifteen seconds until completely liquefied. From there place in a strainer and allow the liquid to strain through, stir the bit in the strainer to help the last of the liquid to pass through the screen.
I usually place this in the fridge afterwards for it to chill and also for any bubbles to escape to the surface of the liquid.
And here you have fresh aloe vera gel! It’s meant to be used right away because it will oxidize and there is no preservative to protect it from mold and bacteria. If you want to save any portion of this for another day I suggest freezing it into ice cubes. This batch is going right into my soap as soon as it is cold enough.
