Questions & Answers about Het mengsel is langzaam ingekookt.
Why does this sentence use is instead of heeft for 'has boiled down'?
Because the verb inkoken (to boil down) describes a change of state happening to the subject (het mengsel), making it intransitive here. When a verb shows a subject changing state without a direct object, it uses zijn in the perfect tense. If someone else were doing the action to the mixture, it would take a direct object and use hebben instead (for example: 'De kok heeft het mengsel ingekookt').
How is the past participle ingekookt formed?
It comes from the separable verb inkoken. To form the past participle of a separable verb, the ge- prefix is placed between the separable part (in) and the verb stem: in + ge + kookt.
Why does ingekookt end with a -t instead of a -d?
This follows the 't kofschip rule, which you may remember from earlier levels. The stem of the base verb koken is kook. Because the final letter k is a voiceless consonant (it is in the word 't kofschip), the past participle gets a -t instead of a -d.
In English, 'is boiled down' describes a current state, while 'has boiled down' describes the completed action. How does Dutch handle this difference?
Dutch uses the exact same phrasing for both! Because state-change verbs use zijn for their perfect tense, Het mengsel is langzaam ingekookt translates to both 'The mixture has slowly boiled down' (the completed action) and 'The mixture is slowly boiled down' (the resulting state). You rely entirely on context to know which nuance is meant.
