I am hoping to find an oil substitute, better than just applesauce, to coat the flour in a recipe. Would ground flaxseed added to the applesauce help?
the containers of ground flaxseed at our house said they work as a substitute for eggs as a binder in baking not oil,
consider using different typs of fat substitutions (sourcream, avacado, coconut oil--which is actually a solid at room temp, or as someoen said earlier yoguart) be prepared for trial and error...and also consider if you change the flour to a nut meal you can cut down the amount of oil (meals contain more oil than flours)
I depends on what you're using it for. Without more details, its difficult to know for sure.
In general, flaxseed oil can be used as an oil, but has a more limited number of uses. For instance, if you wanted to dress a salad with flaxseed oil, it would be fine and may even add a unique flavor to your salad.
However, from your question, it almost sounds like you want to use it to bake or fry something with the flaxseed oil. I would recommend against this. Flaxseed oil starts to smoke at about 225F, at which point all sorts of nasty compounds are created, in addition to filling your kitchen with smoke. There are many other oils out there that withstand heat much better, and don't smoke until 435F or 440F. If you're after the omega 3 oils in the flaxseed, try sprinkling some ground flax over your finished product.
Essentially, if you want to use flaxseed oil for something that is not heated, go for it, otherwise, stick with good quality canola or peanut oil.
