These are 10 cooking utensils used by cook-casters and Meal Magicians. Yes I know one of your players wanted to play a Kitchen Wizard, don't lie. Everyone has once. Also; you can finally use this as a unique loot table for whenever the players raid the obligatory kitchen area in a dungeon.
This giant metal pot with sloped sides is made of adamantine. Besides being both unbreakable and scratch proof, the adamantine actually disperses and transfers heat incredibly well- this leads the pot to have excellent cooking ability. You can't burn or overcook specific items in your pot- grant advantage to all cooking rolls or whatever for using this pot. Also water boils super fast too- you can boil water in less then a turn, so assume any rest period you have sanitized water even from a dingy small flame.
You can also use this as a +2 magic shield in a pinch that grants you +2 AC. Small beings like halflings or kobolds could also use this like a sled or be carried around in it like if they're injuried, or they could like cower under it like a protective dome which will make them immune to all damage unless somebody pulls the wok up.
 Death Whisk
It's a metal whisk. The handle is steel and the long prongs stick out in a geometric pattern. Most medievaly people would just use wooden twigs if they need a whisk, so this metal whisk is unusual in the fantasy world.
Beyond being a useful kitchen appliance to create froth and batter- this whisk is also a deadly weapon. But only to creates that could be added to the whisk's mixture. Tiny gremlins, bugs, shrimp and the like could be added to a batter and spun up. The whisk magically melts them into the mixture- creating both an edible and kind of gross slurry of meat and body parts. Even without a mixing bowl, you could slash this whisk around against a swarm of insects and create a black, fluffy cream.
 Basilisk Oil
While this technical isn't a piece of cooking “equipment”, it is both a useful tool in the kitchen as well as an ingredient. Made from a basilisk, obviously. When you loot this, you find a bottle with about a year supply if only used sparingly and/or on dungeon expeditions. It also doesn't go bad either, so even centuries old bottles are still fresh and have a unique but pleasing “reptile” odor to them.
The basilisk oil has two functions. First, it can be heated to insanely high temperatures and it doesn't explode when water or wet food is added to it like normal oil- making it very safe. No need to roll a saving throw to avoid starting a huge cooking fire. This heat also makes it incredibly dangerous if you actually threw it on somebody as an improvised weapon- deal 1d8+1 fire damage if you throw this wok up in some monster's face.
The second ability of the basilisk oil is that it works as a magical depetrification spell effect, but only on things you intend to cook. You couldn't bring back the stone victims of a basilisk, but you could eat any pieces of the statue you break off and deep fry in the oil.
 Silver Ladle
This magical ladle is made of silver. As silver, it has powerful properties against negative magic and toxic substances. This ladle has two abilities. First- if placed inside a stew or broth which has been poisoned, the holder of the ladle will automatically know it was poisoned- the ladle's handle will vibrate secretly in their hand, with a more powerful vibration the more powerful the poison.
The second ability of the ladle is that it can concentrate poison. If placed into a container of water and the magic words are spoken aloud, it will suck up all the poison within the container of liquid into the ladle itself, which is lifted out of the soup. The ladle will have all the poison and the soup or liquid will be safe to drink- the ladle will have concentrated poison which can be applied to your weapons or stored in a vial without losing any potency. The faded magic words are written along the length of the handle and can be deciphered by anyone who can read ancient runes; it roughly translates to “Mother knows best.”
 Devil's Cookbook
The classic evil magic culinary artifact. It is a heavy ancient tome bound in red leather. All of the pages are blank. If you spill the blood of a creature onto the page, the blood of that creature will form into letters and pictures which details recipes on how to cook it. The more blood is spilled, the more detailed and delicious the recipes become.
The book is found with all blank pages, and it has 111 pages. If you fill up all the pages with blood, the devil will appear in your dreams to offer you the second volume. For this volume, it requires blood as well as urine of each creature. For the next volume, more bodily fluids, and so on and so on. Obviously, there are six volumes, and the degenerate scrumptious feasts of the final volume are a highly prized arcane secret.
 Elven Cheesecloth
This is a light gray, silvery cheesecloth made of magical elvish Glint. This cloth is used to form incredibly long lasting, delicate, and delicious cheeses. As long as any item of food is wrapped in this cloth (not just cheese) it will never spoil or go bad. The same applies to drinks if this is used to plug up the bottle, but wine does not age while stuffed as the seal is too magically perfect and the wine is too perfectly preserved to age properly. However, if this cheesecloth is used on anything other then cheese, it has a 1 in 6 chance to fall apart and be destroyed when the item is unwrapped.
The magical cheesecloth can also be used as a filter. If used to strain nuts, juices, or other fluids it can purify them to a magical degree. You could also use this as a make-shift filter for blood- draining the blood of a victim infected with a disease, running it through the cloth, and then having them drink the blood again will have a 1 in 6 chance to purify their blood disease. Once again, this is an “improper” use for this Glint item, and as such it will have a 1 in 6 chance to permanently ruin it for using it as an impromptu medical item.
 Blast Kettle
This kettle is made of a heavy iron, dark in color, and very dense. However it is also very insulated and feels warm to the touch- hot water put within seems to last for hours, making it a very good source of heat in a very cold place. The kettle will also repair itself magically- dents or shards broken off will slowly form together back in place when nobody is looking- pieces seem to just reappear back together in a little pile of metal shards. With the helpful hand of a person trying to fix it; pieces will snap back into place if just put in the right spots. As such, its essentially indestructible.
Because of these two properties- the blast kettle has found itself with a strange use. If filled with boiling hot water and then the hole is closer by its valve, the heat and pressure will build up inside and it can be thrown like a bomb. The hot water and steam explosion deal 1d4+1 damage to all adjacent enemies to where you throw it. Then, once the bomb has gone off, you can pick up a few of the bigger pieces and just put it in a bag and wait for it to magically put itself back together again.
 Striking Chef Hat
This is a bright red chef's hat, which gives the impression of a powerful, high ranking chef. Wearing this hat counts as a +1 magic piece of armor granting +1 AC. This bonus only applies as long as the person wearing it is clean and orderly- food or blood splatter will spoil the magic until they are totally clean and respectable again.
This chef's hat also has a special ability. Once per day, the wearer can cast a Command spell, but only for actions related to cooking. For example, they could command an orc holding a pan to start scrubbing it, and the Orc would squat over the campfire while trying to scrub the pan clean against their will, screaming for help as their body serves the magician. Another is to force an enemy to start oiling themselves up with sauce, which would make them be more appetizing to a dungeon monster. This ability only works against intelligent opponents- but can work on animals or monsters who actually "cook" or prepare their food.
 Vegan Cleaver
The weapon appears as a large butcher's cleaver, capable of cutting through tough slabs of meat or even bones. Essentially it acts as a +1 magic sword. It has a green colored metal blade with a white, diamond encrusted cutting edge and a floral motif etched along the spine of the blade. Stats as a +1 magic sword, so 1d6+1 damage.
The cleaver has a special effect over all meat it severs. Every body part chopped off by this cleaver or any piece of prepared meat butchered with it magically transforms into a plant-based material similar to tofu or roughage. Blood seeps out as sap, bones become like hard shoots, skin becomes like a leaf wrap. The meat maintains its same color and look, it's just become edible for herbivores. Also, any body chopped up by this spell becomes useless for traditional necromancy, though druidic magic could rise it against as a deadfall/walking wood style undead being instead.
 Cursed Butterchurn
This large wooden butterchrun is used to create butter. It is a plunger type that requires a bit of elbow grease to fully use. It smells a bit off and the touch of a Sage can clearly feel that it has been cursed by dark magic. Nonetheless, it can still be useful in some situations to those who know how to make use of the curse.
Normally, a butterchrun is plunged to turn milk into butter. This butterchurn instead begins to putrefy any milk put into it and churned, making it chunky and disgusting. If it is continued to turn for a full three exploration turns, the milk will change from butter into a protoplasm putrid slime with 2+2 HD and an acid attack that deals 1d6 damage on a hit. The slime is mindless and will seep out of the butterchurn as soon as it is opened again. You can hold the butterchurn by the handle like a two handed weapon and bop and enemy on the head to release the slime on them.
