Unfortunately this is not a feature we have within the Meal Packs or Cookbooks app. We are different from recipe box apps/companies because we do not supply any food for our recipes- we supply the method, equipment and some fab audio guides over the top! Other recipe box apps/companies who do provide the food can be sure of the exact ingredient and macro breakdown they're sending out, but because we get you guys to buy the food yourselves; we cannot guarantee the exact brand/specify product we can't provide that information for you.
With customers buying their own ingredients it becomes a lot harder- for example we'll never be able to know the % of fat in the mince that people buy or the weight of the vegetables that you purchase, so we'll always be mis-representing the calories or macros which would not be helpful for anyone due to the significant level of inaccuracy. We do have a few customers that use our apps in conjunction with calorie counting apps, which works really well for them and we do have a blog full of twists that can assist with any changes to ingredients that can't be sourced/dietary requirements and this can be found here:
We hope that explains this a little further for you and if you have any further questions please do let us know on email@example.com
