Cylinders under sauce (5)
I believe the answer is:
penne
'cylinders under sauce' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for penne that I've seen before include "2 [PASTA]" , "Pasta in thick tubes" , "Tubular pasta" , "Tube pasta" , "Pasta in the shape of tubes" .)
