Are encore and toujours interchangeable in this situation? Le rôti est encore au four?
Generally, only one preposition will be correct, and any others will be ungrammatical or change the meaning. I couldn't tell you why it's "à" and not "dans" here though.
The only thing I can think of is that with food you use "à", e.g. "biscuit au chocolat" - "chocolate biscuit". If you're not talking about cooking food in the oven, you do use "dans le four".
Linguee seems to suggest that "au four" means "baked"/"baking" (and presumably "roasted"/"roasting").
Since 'toujours' also means always, shouldn't 'The roast is still in the oven.' be accepted as well?
I believe that is what is at the top of this discussion. Perhaps you were asked to translate into English, then you have the correct answer. I was asked to write what I heard in French. If you were also asked to listen to French, then your answer needs to be in French. Hope that helps
I think both "still" and "always" should be accepted. "The roast is always in the oven" makes sense, doesn't it?
To me, they mean very different things. The roast is still...means that no one has gotten it out yet, or it is still roasting...that is, its not yet ready to eat because it needs to cook more. The roast is always...is strange because it implies that is where the roast "lives" or is stored. Since raw meat needs to be refrigerated, it will NOT always be in the oven. It will only be in the over while its cooking.
Here is the situation. A & B are preparing for a dinner. After a couple of hours, A starts to get the food to the dining room, as the guests are arriving & B is still working. B comes back to the kitchen & asks "Where is the roast?" A answers "It's always in the oven", not looking at B & is still working on the final touches.
Yes, I can see how people could say that in reference to how they usually cook their meals, and that they usually always have a roast when guests come to dinner. I try to go with the simplest answer as I'm really a beginner, so I'd rather learn the simple answers first to aid understanding; and add more complex constructions later.
