you shoud have "aparat"
Not metal though. All glass is best.
A recipe I've known for along time:
1 kg wallnuts picked about 1 month before their shells get hard. You need to be able to chop them with a kitchen knife.
1 kg sugar
1 liter 95% (or better) spirit.
Chop walnuts into small cubes. No peeling. Use the whole fruti. Gloves are recomended or your hands will be stained for weeks. Mix sugar, nuts and spirit in a glass container you can seal. Let stand for at least 90 days.
Yummy, in small quantities (15 to 50 ml) great for colds . Not good to get drunk with - mega hangover.
