The Millstone: Animal-Powered Ore Doubling and Dyes
The 
Millstone in Kaleidoscope Cookery is an ore multiplier that needs no fuel and no redstone - you harness an animal to it and it turns. That makes it one of the cheapest ore-processing setups in any modpack it appears in, and its 85 recipes reach a lot further than the cooking mod it ships with.
Building one
The recipe is a wooden fence on the top centre, a 
Stick and a 
Grindstone in the middle row, and three 
Smooth Stone across the bottom. Every part is early-game, so the millstone is available long before a furnace array would be.
Using the Millstone
Three steps, and the animal is the engine:
- Load it. Right-click with items in hand to insert them. Items dropped onto the millstone from above are pulled in automatically, which is what makes hopper and dropper feeds work.
- Harness an animal. Certain creatures placed by the millstone can be hitched to it. A donkey is the classic choice and the mod gives you an advancement for using one.
- Wait one rotation. Once the animal is walking, the stone turns. After one full rotation the loaded items are transformed and ejected out of the opening.
The sound cue is a low churn, so you can hear from across a base whether the mill is still running or your animal has wandered off.
Ore multiplication
This is the reason to build one even in a pack full of industrial machines. Raw ore blocks go in whole and come out multiplied, with no fuel cost at all:
Iron Ore or 
Deepslate Iron Ore into 3 
Raw Iron
Copper Ore or 
Deepslate Copper Ore into 5 
Raw Copper
Gold Ore or 
Deepslate Gold Ore into 3 
Raw Gold
Coal Ore or 
Deepslate Coal Ore into 3 
Coal
Redstone Ore or 
Deepslate Redstone Ore into 7 
Redstone Dust
Lapis Lazuli Ore or 
Deepslate Lapis Lazuli Ore into 7 
Lapis Lazuli
Diamond Ore or 
Deepslate Diamond Ore into 2 
Diamond
Emerald Ore or 
Deepslate Emerald Ore into 2 
Emerald
Nether Gold Ore into 5 
Gold Nugget, and 
Gilded Blackstone into 3 Gold Nugget
Block of Amethyst into 3 
Amethyst Shard
Silk Touch is the prerequisite for all of these, because you need the ore block itself rather than its normal drop. Pair a Silk Touch pickaxe with a millstone and your effective yield beats Fortune on most of the list.
Dyes, three at a time
Flowers grind into dye at rates a crafting table cannot match. Single-block flowers give two dye each and tall ones give three:
- Two dye each from
Poppy, 
Red Tulip, 
Beetroot (red), 
Dandelion (yellow), 
Cornflower (blue), 
Blue Orchid (light blue), 
Allium (magenta), 
Orange Tulip and 
Torchflower (orange), 
Azure Bluet and 
Oxeye Daisy (light gray), 
Lily of the Valley and 
White Tulip (white), 
Pitcher Plant (cyan), 
Wither Rose (black), 
Cactus and 
Fern (green), 
Pink Tulip and 
Pink Petals (pink) - Three dye each from
Rose Bush (red), 
Sunflower (yellow), 
Lilac (magenta), 
Peony (pink), 
Large Fern (green)
Wool is on the same list from the other direction: any of the sixteen wool colours grinds back into 3 String, which turns a sheep farm into a string farm.
Food and farm processing
Wheat into 
Flour, the base of the mod's dough recipes- Any seeds into
Oil, the fat every wok recipe needs 
Rice Panicle into 3 
Rice Seed
Bone into 5 
Bone Meal, well above the vanilla three
Oil is worth calling out. The alternative source is killing pigs, piglins or hoglins with a kitchen knife, which is slow and finite. A seed farm feeding a millstone is renewable and unattended.
Stone and terrain shaping
The millstone also does the jobs a stonecutter cannot:
Stone into 
Cobblestone, and Cobblestone into Smooth Stone - a fuel-free path around the furnace step
Andesite, 
Diorite, 
Granite, 
Basalt, 
Smooth Basalt, 
Blackstone, 
Deepslate and 
Cobbled Deepslate into their polished forms- Gravel into
Sand, and sand into the matching smooth sandstone 
Flint into 
Gunpowder
That last one deserves emphasis: a gravel supply becomes a gunpowder supply with no mob farm involved.
Automating it
Because items dropped from above are inserted automatically, a hopper or dropper above the millstone handles input without any special machinery. The animal is the part that cannot be automated - it has to be a live creature, hitched and moving - so the practical setup is a fenced pen with the millstone at its centre and a feed line running in from a farm.
