How to talk about dishes
Il faut des produits frais
Il faut faire quoi ?
Ça a l'air bon
Il faut tells you what you need or what you need to do. It never changes, whatever follows it.
Il faut can be followed by nouns:
Il faut du vin blanc et des oignons
You need white wine and onions
Or it can be followed by the infinitive of verbs:
Il faut compter 20 minutes
You need to wait 20 minutes
You'll also hear il faut followed by que:
Il faut que ça mijote
It must be simmering (literally, it's necessary that it simmers)
'Ça a l'air ...' is a useful catch-all expression to say how something seems, looks or smells.
Ça a l'air bon.
That looks good.
Ça a l'air délicieux.
That smells delicious.
Il faut du persil et de l'ail.
You need parsley and garlic.
Il faut compter une bonne demi-heure.
You need to give it a good half-hour.
Vous avez l'air occupé.
You look busy.
