Is it possible to work out how much a given cake, pie, etc will weigh and how much fat, salt etc it’ll contain after it’s made?

There are various websites that will do that for you. [Here’s](http://recipes.sparkpeople.com/recipe-calculator.asp) one.

Is there anything which can do something similar for weight?

[Caloriecount.about.com](http://Caloriecount.about.com) will allow you to use weight for ingredient input. You have to figure out “servings” on your own.

As for final weight, no. I think there are too many variables for that to be at all accurate. Variables include oven temperature, duration of time cooked, and relative humidity to name a few.

Best bet would be to make the item in your kitchen 3-4 times and use an average.

Unlike most foodstuffs, tarts generally taste worse when they weigh more.

I was afraid of that. :o

Thanks though.
