Quarry bushes may be processed at a farmer's workshop into bags of quarry bush leaves, which then must be cooked at the kitchen to be edible. You will need an empty bag to be available for this task. Quarry bushes cannot be brewed into alcohol.
Processing quarry bushes at a farmer's workshop requires one bag, and will produce 5 quarry bush leaves (and one rock nut) for every plant in a given stack of quarry bushes. Quarry bush leaves will be removed from their bag if taken for cooking while still in a farmer's workshop.
Cooking quarry bush leaves can result in very large stacks of Prepared Food, thus saving space and barrels. In a fortress that relies on selling large expensive stacks of Prepared Food, quarry bush leaves are great filler: a lavish meal made from whip wine and dwarven cheese with two stacks of quarry bush leaves for filler is worth almost ten times more than an easy meal made from wine and cheese alone.
 Rock nuts
Quarry bush seeds are known as rock nuts. Although their material definition marks them as being edible raw, dwarves will not eat them.
Rock nuts can be milled at a millstone or quern into rock nut paste, using the job to mill seeds/nuts to paste. This paste can then be used in cooking, or pressed at a screw press into a rock nut press cake and a jug of rock nut oil.
Both the rock nut paste and rock nut press cake are cookable and considered a single food category, referred to as "rock nut" in the cooking permissions screen (not to be confused with "rock nuts", the entry for the seeds), the Stocks screen compacted view, and Prepared meal descriptions.
The rock nut oil can be cooked or used in place of tallow to make soap.
Use moderation when commanding rock nuts converted to paste - the nuts are required to re-plant the crop; if you grind up your entire supplies, you can't grow new quarry bushes.
The main attraction of grinding up rock nuts is the production of rock nut oil as soapmaking ingredient. Both the globs of paste and the press cakes are minimum-value cooking ingredients, at 1☼ each. When looking at cooking ingredients, the quarry bush leaves completely overshadow what can be gained from an oil-pressing operation.
 Plant Gathering
Due to a quirk in the Raws, a wild Quarry Bush plant growing underground (not planted) can yield 6 leaves if placed in a Gathering zone. An Herbalist will first harvest a single leaf growth, then collect the entire plant, which can be processed as usual afterwards for 5 more leaves.
 Food Value
Thanks to the increased value of rock nut oil as a by product of rock nut processing, the highest potential value of products gleaned from one quarry bush plant is 56 (five leaves at a value of 10 each, plus oil and a press cake).
