I am thinking candied buddha hand bc I love sour candy (i think it must stimulate my vagus nerve or some good neuro chemicals lol). I looked at diy steam distillation for essential oil, which is doable but seems tedious. Or letting it sit in high proof alcohol and using in cooking in the future.  

 This fruit has whites that Are usable unlike lemon or lime.
A nice way to use this is shaving it over icecream 🤌🏻
