I don't think there are calories being added. Just water. This assumes that the calories listed on the box are correct - and you're right, they are usually close enough.... the nutritional values are calculated from the production process (the manufacturer has some stake in making sure that portion sizes are accurate - portions mean money to the manufacturer).

The water, I guess, would come from the freezing process.

I sometimes make frozen meals from homemade, and the texture does change when I look at the thawed or thawing product. Mainly because water has accumulated on the surface of the mashed potatoes, for example, and then the method of cooking determines what happens to that water (does it bake off in high heat or just get reabsorbed? depends...)

However, what I put in the foil pie pan doesn't change as far as calories go, that I am sure of!

That's my reasoning about frozen foods. I just go with what they say. Sure, there's variation, but, like money, the producer has a strong interest in keeping the portions uniform.
No water is added or taken away by freezing. Any ice on the product came from the water in the food itself.

I posted this because some people are concerned about the calorie counts on packaged food being inaccurate. This still isn't a full proof method, but if someone is concerned about this, this is more accurate than going by the calorie count on the package.

There IS a significant difference sometimes in the amount of calories in the food versus the amount of calories listed on the package. If you're generally eating a low calorie diet anyway it might not matter, but some people count all their calories up and still don't lose weight because the discrepancy.

I've noticed many times if I weigh out an amount of food that it's often more than what is listed on the package as being in that package.

Try it for example with a bag of goldfish crackers. The bag says 187 grams of crackers are in the bag, but if you pour it out and weigh it on a food scale, there's a good chance there could be 195 or even 200 grams in the package.

This is for people who want a seriously accurate calorie count. Some people count calories per the package and are still struggling. This is a way to help them to be able to reach their goals.
