Is there a way to calculated the weight and nutritional values of a tart from its ingredients?

Factual Questions
1

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?

2

There are various websites that will do that for you. Here’s one.

3

Is there anything which can do something similar for weight?

4

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.

5

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