Storing fermented lemon peels

Total newb to fermenting but I watched a youtube video about fermenting lemons which I did and got delicious punchy lemon peels to chop and top onto any dish. However, I'm not sure how to store them safely. Do they have to stay under the liquid / weight forever like when you're actively fermenting them or can I drain them, cut them all up, and put them in a small tupperware container to grab from whenever? I would just keep them in the original jar under the liquid / weight but the lid has become super rusty so I want to transport them to another container.
