so first time making duck confit at home and i've only made it in school before that. my questions are... can i freeze the duck? half is shredded off the bone, some is still in tact also if i was to just refrigerate it how long could it potentially last? currently it's all being held in air tight bags in my refrigerator, i was told i can freeze the duck in mason jars covered with the duck fat.. is this true? any tips would help thanks!
