Growing up my mom always cut the back of the turkey off when she made a turkey. One day i asked her why she did that. She replied. IDK thats how my mom always did it. I left it alone and then years later my mom was making a turkey and her mom was ther also. And my mom cut the end of the turkey off, Her mom stopped her and asked her what she was doing. and she repiled isnt that how you always did it growing up? Her mom said " oh darling, our oven was just to small to fit the whole bird in"
Not really my mom but i heard it somewhere.
