I believe the answer is:

manna

I'm a little stuck... Click here to teach me more about this clue!

'it taste heavenly?' is the definition.
The definition suggests a singular noun which matches the answer.

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for manna that I've seen before include "Heavenly grub?" , "Biblical food for Israelites in wilderness" , "Food from heaven for Israelites with Moses in the desert" , "unexpected windfall" , "Special food" .)

I've seen this clue in the Evening Standard.
