I don’t have my conversion chart handy, but isn’t 170 Celcius like a Thousand degrees Farenheit? I think they’re trying to cover themselves from a food safety standpoint.
You are talking about two different things:
170’F = 77’C
170’C = 338’F
Google says to cook chicken at 350’F, which is pretty close to 338’F. You want an internal temp. of 165’F, and I imagine you could get that either way just by controlling cooking time (slightly longer at 338’F).
ETA: Yes, it appears to be a typo on the package, F for C.
Second thought: the (170F) could mean bake it until a meat thermometer indicates an internal temperature of 170’F. That seems less likely than the typo theory, though.
ETA: Ninja’d!
I think that’s less likely, though, because it’s unlikely that the box wouldn’t indicate a setting for the oven.
I Googled a picture of the package with US instructions. It gives a preheat temp. of 375’F, and different internal temperature doneness times for different meats. The chicken looks to be 165’F. If the Canadian government recommends a higher temp., I would expect to see that on the Canadian box.
I’m not sure why the confusion, because these instructions are very clear that the higher temp. is the preheat/bake at temperature, and the lower one is the internal temp. for doneness.
Are Canadian products never labeled in Fahrenheit?
I’ve never seen cooking temperatures given in Celcius before in Canada. That’s why I wondered if they meant internal temperatures, but you’re right, it doesn’t make a lot of sense that they wouldn’t mention an oven temperature at all (and I’d bet that most people making Shake 'n Bake wouldn’t be using a meat thermometer for it)
Not the best instructions but it pretty unambiguously means bake to an internal temp of 170F. 170F is the parenthetical clarification of what done means.
