Urge control about introduction of dry culinary ingredient (3-6)

'culinary ingredient' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'urge control about introduction of dry' is the wordplay.
'urge' becomes 'egg' (as in egging someone on).
'control' becomes 'power' (I've seen this before).
'about' means one lot of letters goes inside another.
'introduction of' indicates taking the first letters.
The first letter of 'dry' is 'd'.
'power' going around 'd' is 'powder'.
'egg'+'powder'='EGG-POWDER'

Can you help me to learn more?
