in which context would i say such a sentence? as I understood aorist refers to habits or things i do in general, right?
this sentence is little awkward. yengeç pişiriyorum is more natural. but if you want to say i cook a crab every sunday, then you say her pazar yengeç pişiririm/pişiriyorum
Why is "crabs" incorrect?
Because it says "bir," which means "one/a"
