Here are all the forms of “pot”, including searching for it as a verb and checking for “pottery”.  As a vessel for holding liquids or solids, it has both Germanic and Latin roots, but the etymology seems to be uncertain.  Oxford English Dictionary tells us:

The word in the Germanic and Romance languages and in post-classical Latin perhaps ultimately shows a loanword from a pre-Celtic language (perhaps Illyrian or perhaps a non-Indo-European substratal language), although a number of other etymologies have also been suggested.

Welsh pot (15th cent.), Irish pota (1475), and Scottish Gaelic poit are all apparently < (earlier than) English.

Please, fellow scholars, when you are charting and discussing “pot” note that sometimes pots carry food and other times they are for gold.

• 02.001 Nearly every pot
• 02.086 So they got a great black pot,
• 02.113 to pots full of gold coins standing
• 02.116 So they carried out the pots of coins,
• 02.117 and carried away the pots of gold,
• 06.074 Roast ’em alive, or stew them in a pot;
• 07.126 and red earthenware pots of honey,
• 12.011 like the noise of a large pot galloping on the fire,

Like “fat”, most instances of “bone” don’t seem to be about food – yet some are.  You be the judge as you are tracking the food mentions in The Hobbit!

• 02.113 There were bones on the floor
• 05.054 the cat has the bones’ that of course is the answer,
• 05.087 He still had a bone or two left to gnaw,
• 06.078 fat melts, and bones black
• 08.110 and leave your bones
• 12.091 in my bones that this place will be attacked again.
• 13.046 and bones were upon the floor
• 14.043 There for ages his huge bones could be seen
• 18.021 in his bones for the homeward journey.

None can say better than Leonardo da Vinci:

“Water is sometimes sharp and sometimes strong, sometimes acid and sometimes bitter, sometimes sweet and sometimes thick or thin, sometimes it is seen bringing hurt or pestilence, sometime health-giving, sometimes poisonous. It suffers change into as many natures as are the different places through which it passes. And as the mirror changes with the colour of its subject, so it alters with the nature of the place, becoming noisome, laxative, astringent, sulfurous, salty, incarnadined, mournful, raging, angry, red, yellow, green, black, blue, greasy, fat or slim. Sometimes it starts a conflagration, sometimes it extinguishes one; is warm and is cold, carries away or sets down, hollows out or builds up, tears or establishes, fills or empties, raises itself or burrows down, speeds or is still; is the cause at times of life or death, or increase or privation, nourishes at times and at others does the contrary; at times has a tang, at times is without savor, sometimes submerging the valleys with great floods. In time and with water, everything changes”

• 05.050 in the water,
• 05.056 He flapped into the water
• 05.108 down to Gollum’s water.
• 05.122 for he was leaving the water further

• 09.061 and there it was joined to the main water of the Forest River
• 09.061 There was a dim sheet of water no longer overshadowed,
• 09.061 Then the hurrying water of the Forest River

Sometimes it is a comforting consumable, sometimes it is a choking hazard.  Please be discriminating, dear colleagues, when using these words to make generalizations about food.  You will find “smoke-hole” and “smoke-ring” in their own entries.

• 01.002 a very comfortable tunnel without smoke,
• 01.006 smoking an enormous long wooden pipe
• 01.010 and blew out a beautiful grey ring of smoke
• 01.068 and found Thorin with his feet on the fender smoking a pipe.
• 01.081 The mountain smoked beneath the moon;
• 04.013 and blew smoke rings,
• 04.035 into a tower of blue glowing smoke,
• 04.036 and the smoke that now fell from the roof
• 06.064 in coloured sparks and smoke.
• 06.072 Soon they had a ring of smoke
• 06.072 Smoke was in Bilbo’s eyes,
• 06.084 of sparks and smoke.
• 07.045 and the smoke was rising to the blackened rafters
• 07.102 and flying smoke was in the air.
• 07.116 this is a splendid place for smoke rings!’
• 07.116 he was so busy sending smoke rings
• 08.072 in black smokes.
• 11.008 and a dark smoke.
• 11.010 or I imagine so from the smoke,’
• 11.011 and still I expect smokes
• 12.013 and wisps of smoke,
• 12.021 the hall smoked,
• 12.042 that smoke on a gentle wind

Only one mention!  We don’t know if one enjoys cow milk, goat milk, or coconut milk in Hobbiton.

• 01.065 Pour the milk on the pantry floor!

Well here’s glimpse at my own prejudices – I read right past the word “fat” several paragraphs back because it struck me as a descriptive adjective.  Then I made it to paragraph 1.065 and the dwarves sing of treading on the fat.  The fat in question seems to be a kitchen supply, such as lard, and reminds me that “fat” is a foodstuff.  Here we go!

• 01.004 They are inclined to be fat
• 01.050 For one thing Bombur was immensely fat
• 01.065 Cut the cloth and tread on the fat!
• 02.046 for a nice bit o’ fat valley mutton like what this is.”
• 02.067 “You’re a fat fool,
• 03.028 “He is too fat to get through key-holes yet!”
• 04.046 said poor Bombur, who was fat,
• 06.078 fat melts, and bones black
• 07.087 He was fat,
• 07.121 and fat again on bread
• 08.026 You should not be so fat.
• 08.033 Bombur slept on with a smile on his fat face,
• 08.084 They’re not as fat as they might be.
• 08.088 With that one of the fat spiders ran along a rope
• 08.096 Old fat spider spinning in a tree!
• 08.096 Old fat spider can’t see me!
• 08.101 you are fat and lazy.
• 08.123 and stabbing at their fat bodies if they came too near.
• 10.015 Poor fat Bombur was asleep or senseless;
• 10.038 and they quickly grew fat
• 11.018 I am too fat for such fly-walks,’
• 12.060 though it was fat enough.
• 15.059 except perhaps old fat Bombur and Fili and Kili.
• 16.010 grumbled the fat dwarf.

Do you suppose that “appetite” and “hungry” are food words?  Let’s include them and their ilk.

• 01.060 (his appetite was quite taken away),

Only in Bilbo’s and Beorn’s houses.

• 01.058 and things piled up on big trays,
• 01.059 they had whisked the trays
• 01.063 not waiting for trays,
• 07.093 others bore on their broad backs trays with bowls

The other instance of “plate” may be found under “gold-plated“.  I had always assumed that this word was related quite directly to “flat”; the sources of the word turn out to be a complex and lovely dance between words for “flat” and for various metals – which can be presented as flat bits or plating, but not necessarily.

• 01.058 and glasses and plates and spoons
• 01.060 the plates and glasses.
• 01.063 balancing columns of plates,
• 01.064 Chip the glasses and crack the plates!
• 01.067 So, carefully! carefully with the plates!
• 07.116 At last Gandalf pushed away his plate
