Splendid display of unlimited beer in kitchen cupboard (9)

I believe the answer is:
pageantry
'splendid display' is the definition.
(I've seen this before)
'unlimited beer in kitchen cupboard' is the wordplay.
'unlimited' means to look at the middle letters (remove the limits/outer letters).
'beer' becomes 'lager' (type of beer).
'in' means one lot of letters goes inside another.
'kitchen cupboard' becomes 'pantry' (I can't explain this - if you can you should believe this answer much more).
The centre of 'lager' is 'age'.
'age' inserted within 'pantry' is 'PAGEANTRY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for pageantry that I've seen before include "Splendid display" , "Spectacle" , "Show" .)
