Yes, you can use Bisquick as a substitute for flour in this recipe.
no not at all
That depends on what you are making. Bisquick is just a biscuit recipe without the wet ingredient's.
I often use flour (all purpose) in recipes calling for bisquick. I just add a little bit of baking powder and a tiny bit of salt.
It all depends whether it is a sell by date, use by date, or a best before date. If it is a sell by, then that would be an earlier date than an 'eat by' date so it would probably be OK. If it is a best before, then it probably won't taste as good but will still be safe; if it is after a use by date then it may not be safe so you shouldn't eat it.
It is not recommended to use sour cream past its expiration date as it may not be safe to consume.
Any can liquid or food can be used after expiration date about 5 months. I tried it and nothing happened.
The Betty Crocker official website has many quiche recipes that use Bisquick since they produce this product. Also cooking websites such as Cook, Yummly, and Recipe Source have Bisquick quiche recipes as well.
No, it is not safe to use buttermilk past its expiration date as it may have spoiled and could cause foodborne illness.
i wouldn't use it since it has milk
Well it really depens on how long it was after the due-date if it was a week its o-k and if it was a month well it might not be to good to eat!
Use system restore.
