Lovemychickens is right. Chicory used to be used as a coffee substitute. Otherwise known as bachelor buttons I think. The light blue flower that grows on roadsides all over the place in West Virginia anyway. The root is roasted and ground. I think some brands of coffee even blended some chicory in back in the day. You can also make mint tea, yum. We have a huge sassafras tree in our front yard and get seedlings everywhere. We dig 'em up and make tea that tastes just like hot root beer. For oil, get a cow or goat and make butter! If it was me, I would definitely go to the store though. I admire you for your efforts to produce nearly all your own food. You are amazing. I could never do it (unless something terrible happened and I HAD to, of course)
