Why not "you should"??
It's not an option in the recipe in this case. And it's not a suggestion. You've come this far, and the next step is that you have to put it in the oven, or you must.
why "you must put the cake in the oven during forty minutes" is wrong
'For forty minutes' not during.
Confused with english
Why not ..."during forty minutes" ???
You should say "for forty minutes".
Er, you put the batter, (or the "cake mix"), in the oven. It doesnt become a cake until it is cooked.
Some bad joke I guess
Google translate says "you have to put the cake in the oven for forty minutes " why is this the wrong answer
COME ON!!! For a simple typo? One letter off pandent vs pendant.
