Now the current problem that I'm facing is that my Cooks won't use Rock Nut Oil in making meals. My guess is that this is a similar case to Dwarven Syrup, but I can't think of how to apply a good workaround.
I have a suggested plan, but i haven't had time to boot up the game to try it - make a 1 tile stockpile per kitchen that takes solid food and feeds into the kitchen, make a large liquids stockpile that feeds into all kitchens. Presto, the cook should usually take only 1 piece of solid food.
I've set up something similar to that. I have a Oil stockpile and a Press Cake stockpile that both feed into a kitchen. The Press Cake stockpile holds just 2 cakes, and so each "Lavish meal" uses up 2 Oil and 2 Cakes, using up the products of the Screw Press in equal proportion.
Quern -> Paste stock -> Screw Press -> Oil stock & Cake stock -> Kitchen.
To get the press cake stocks filled up as quickly as possible (since they are the biggest rate limiting factor) I ordered them to take directly from the Screw Press. Given that they are also the only cake-accepting stockpile in the fort, I'm not sure if it makes a difference, but it makes me feel happy.
Using queued jobs from the Manager's screen, I can largely automate the OilCake production process. Simple "repeat" commands won't quite cut it, since there are frequent short interruptions to supply at the kitchen. The only part that needs direct attention is the leaf-dumping.
Now a number of people have offered suggestions for how to make leaf dumping easier. These are wholly un-necessary, as it is a quick smooth and painless process. The bags are sitting in the Farmer's workshop (no stockpile accepts leaves) which is 3 tiles away from a dumping hole. When I order a mass dumping of leaves via the z-Stocks menu, dwarves swarm over to the workshop,
take the leaves OUT OF THE BAGS, and then dump them in the hole. The dumping could hardly be easier! The only question was what to DO with 2,000 units of leaves sitting in a pile, which is why I installed an Atom-Smasher.
I have enough bags now and my skilled growers are producing large enough stacks that my Leaf-Dumps generally come in batches of 500 or so. Since the leaves themselves are in large stacks, this only requires 30-40 dumping jobs, and since the distance is so short, the bag emptying operation is completed in about 10-15 seconds.
My only problem with dumping was that
I had to do it, and before I crafted a goodly amount of bags, I had to do it
quite frequently. I tend to use "process to bag" on a Repeat command rather than queuing it up with the manager since you receive just one job cancel message when the bags run out rather than seventeen.
I feel much more confident now about the efficiency and practicality of feeding a fort on Rock Nut products. When I ran into the 200 seed limit, I realized that I could mostly get past this by using unprocessed quarry bushes as my seed storage, and only produce seeds when needed.
I learned from this what many people have learned when experimenting with the various manufacturing processes in DF:
You can NEVER have too many bags. I should have set up a cloth industry ASAP to support the bag intensive Nut-extracting business.
