Back of the box (or jar) recipes are usually very reliable.
The food mfg wants you to keep buying the product so they go all out
to come up with delicious recipes you’ll want to make again and again.
I confess to using the chocolate chip cookie recipe on the bag of the irreplaceable chocolate chips.
Although I do add my own touches depending on what’s in my kitchen cupboard.
I use recipes from the internet but I print them out with originator info on them..usually.
