From Zee Marsden
I grow my own herbs and make my own herbed Olive Oil.
I pack a mason jar with whatever kind of herbs I grow: Basil, Thyme, Oregano etc., add sliced garlic, crushed pepper flakes and fill with Olive Oil. Cover with a piece of cheese cloth. DO NOT COVER THE JAR WITH THE LID. Otherwise as the oil heats up it will explode.
With these days being so hot I stand the jar for about five days in the hot sun. Let the sun do the cooking for me. Otherwise I heat the oil in the microwave and pour over the herbs.
Can also be done using dried herbs. These herbed oils I have seen at Farmers Markets upwards of $25.00 per litre.
