If I were describing my favourite food and used compound adjectives, I would use hyphens. For example:
- water-mouthing ice-cream
- freshly-baked cake
- heart-shaped cookies
- soft-melting cheese
The underlined words are compound adjectives because , although they have two words, they are considered as one -word adjective. This is the reason why a hypen (-) is used between the two words; it is to indicate that the word is just one.
