Jars are perfect for lacto fermentating anything

Hi I have a small piece of aloe vera that’s been cut off a bigger plant and it’s spent about a year or two in a pot with some soil and it looked fine until recently I realized that it started to rot and it has no roots but there are new bright green leaves growing from the center. Would it be a good idea to wash the rot off and keep it in a jar like this to wait for the roots to start to growing and then replant it into new succulent soil? Sorry for a random question but you seem to have expertise in this

Is saddle still the best candidate? Like when you move a circle across a circle you get a torus, and when you move a parabola across parabola you get a “saddle”
