Good job. Here are two minor errors I found:
Large should be made up of Mediums.
[CR 2] Potion (Medium Healing) | Small healing potion + Small healing potion
[CR 3] Potion (Large Healing) | Small healing potion + Small healing potion
Actually you can make large ones from small potions with CR 3+ skill, I have been unable to make them from medium potions myself
Why list it twice?
[CR 0] Wood Chips & Branch (x2) | Log + Axe
[CR 0] Branch (x2) & Wood Chips | Log + Axe
Just for ease of viewing some people maybe looking for branches and some looking for Woodchips but not reading whole recipe when skimming through, I know ctrl+f is hard to use but working in a helpdesk environment I try to make things as simple as possible
