It should be "Sometimes I make noodles"
There is no option to report that the English translation is incorrect.
Can membuat be used as 'to cook'?
It can in context, but /memasak/ would be more specifically 'to cook' (and more likely to be used). Also, where I live, I was taught that the word is spelled /mei/ rather than /mi/ for 'noodles'.
has to be 'noodles' in English
Really? Making the noodles yourself!? I translated as 'I sometimes cook noodles' and it was incorrect..
