Making A Cold Oil Infusion
Some plants contain important medicianl oils which are highly volatile, i.e. they escape with heat, and a cold oil infusion retains their properties much more successfully.
1. Pack a large jar with the herb and cover with oil. Seal and leave in a sunny sopt for two weeks.
2. Pour slowly through a jelly bag into a clean jug, allowing time for the oil to filter through the fabric.
3. Squeeze out as much oil as possible through the bag. To make the infused oil even stronger, repeat steps 1, 2 and 3 with the same oil and new amounts of the herb.
4. Pour into clean, dark bottles. Seal and store. Preferably, use small bottles as when opened the oil starts to deteriorate.
250 g (9 oz) dried herb or 500 g (1 1/4 lb ) fresh herb to 500 ml (16 fl oz 2/cups) pure vegetable oil.
