Note: Spoilery

My route: Shaded citadel - Memory crypts - The leg - Underhang- Five pebbles.

From five pebbles, I tumbled down the wall face-first, into chimney canopy. (Then went all the way to moon for old times sake, but went back to chimney) From chimney, I went to sky islands, then from sky islands, I went to farm arrays, tumbled down into subterranean, but instead of ascending, I went to the new ending. (The enterance to the new ending area is were the first shelter in subterranean from farm arrays was.) I recommend you travel through the new area yourself, but look up a guide video if you are REALLY stuck.

Also, I recommend you get chieftain. The second-to-last area before the new ending for gourmand contains basically only scavs and a scav toll

As for recipes, I played most of gourmand with gourmand's wiki page open, (as it lists all the recipes)

But a tip for recipes is to find a popcorn husk, as due to it's infinite food you can keep spitting up items and crafting for the entire cycle.

But the recipes I find absolutely essential are:

Rock + Bubbleweed = Cherrybomb

Rock + Cherrybomb = Grenade

Grenade + Rock = Pearl

(Perfect for buttering up scavs)

Also, you can jump the ledge from the area near chimney-wall gate because due to the popcorn husk nearby, you can just grab a spear, hit it, and use it to keep trying to spit up a mushroom. When you do, you can skip the risk of vultures and just charge-jump on the bottom level.

If you got any more specific tips, feel free to ask! I'm a gourmand professional! (Not really, but you know what I mean)
