Store coriander leaves loose in a paper or plastic bag in the refrigerator for 3 to 5 days.
If you wish to store them for a long period, dry and store them in the freezer by placing them in an air tight container. store them in good paper material cover. curry leaves will give the same flavour and crispiness.
If wrapped in a newspaper, it will last for up to a week. soil remaining on the roots and the stem will cause the methi to become soggy and smelly.
Wrap the mint leaves gently in a dampened paper towel or place the mint in a plastic bag, not sealing all the way so that air can circulate. Do not wrap tightly; trapped moisture will cause the herbs to mold.
Fresh spinach should be stored loosely packed in a sealed plastic bag in the refrigerator crisper, where it will keep for about four days. Do not wash spinach before storing, as the moisture will cause it to spoil.
it's best to keep spring onions in the refrigerator. They contain more moisture than mature onions, so keeping them out at room temperature for longer than a couple of days could cause them to mold. Keep them in the crisper drawer, sealed well in a plastic bag, and they'll stay fresh for about two weeks.
