For my gardening reference, this will be helpful: EVERYTHING you ever wanted to know about GROWING ONIONS. the go-to site! From planting seed, seedlings & sets thru different varieties, to storing. Even includes making an onion braid!
Herbs in "frozen" olive oil is one of my favorite ways to harvest. The herbs don't get dry , brown and brittle in the same way they do when they get frozen in water. They also retain their scent and flavor much more effectively!
