A short guide that gives you the locations of all lost recepies and sum other stuff. Spoilers ahead.
Jimbo's Secret Soup Pot
You can find this item right in the first area. It is the smal ruin at the top left. However youll need a double jump to get there. It will probably take you a few tries. If you cant get it outright come back later with wall climb or Red Dragon Tonic (sword upwards thrust).
Shrine: Toad Pools. Right after the shirne jump up in the small hole in the ceiling. There is a platfom you should be able to land on. Again, if you arent able to reach it, wait for the Wallclimb or Red Dragon Tonic later in the game.
I found it rather helpful as it gives you a nice 20% speed boost
Achy Breaky Smelly Heart
Shrine: Z´s Breakfast Food. Altho its not that hidden, there are multiple routs around it, so maybe someone wont find it. Right after Z´s Breakfast Food, take the lowest Path and continue right. Youll find it eventualy. [Its been already collected in this screenshot]
Firefly King's Heart
Shrine: Z´s Breakfast Food. Same area as the Achy Breaky Smelly Heart, but this time youll go up whenever possible. There youll find the Firefly King. He´ll drop the Firefly King´s Heart.
These can be found if you continue the path of the Firefly King right till the drop. Jump down while staying left. After landing on the shroom you have to jump right. There youll find a few as well as some more Lore.
Shrine: LOHAS Phase 2. Just continue right and up, untill you come into the first "room" with spikes.
Standing on that platform go left, there is a hidden path, be mindful of the spikes.
Be careful when you continue, as there are a bunch of slimes that can be rather dangerus.
Dried Insight Shroom
Shrine: Lohas Marketplace. Follow the normal route till you find one water spirit and two eyeballs.
After defeating them you can get up the hidden passage in the celing (where the waterfall comes out)
Work your way up and treat yourself with a new secret recipe.
Fried Durian Puffs
Shrine: LOHAS Marketplace. You´ll need to follow the rout for awhile untill you find a crafting and cocking spot.
If get up and follow the path youll be met by multiple spiders. The recipe is also in spiderwebs, so dont try to rush it.
Shrine: Railcrossing. When you drop down on the rails, go left instead of right. There youll find a tree with the extra ingredient.
The coresponding recipe can be found a bit further. Make sure to use your dash to avoid dmg.
Super Double Crab Boil
Shrine: Asan Cave. Continue with the path untill after the two Iron Bulls. There will be a small opening in the celing.
There will be some spikes, so be prepared to take some dmg.
Blood Lotus Tea
Shrine: MT Asan Area. Go right untill you have to jump up a ledge. Get on the ledge and the perform walljumps above it.
Pappy Panna Cotton
Shrine: Halcyon Heights Alleyways. There will be a point where you have to go up, look left. There should be an opening.
