In Malayalam/Indian, there's an expression:
Appam thinnal pore, kuzhi ennano!
It literally translates to:
Just eat the appam (Indian pancake). Why count the holes!
It implies that one should just enjoy the final product and need not bother how it originated.
It is usually said by an impatient person when asked too many questions about his product or method.
What could be an equivalent expression in English?
Although it emphasizes gifting or offering perhaps more than the idiom about the holey pancake, 'not look a gift horse in the mouth' is very similar both in use and in intent:
if someone tells you not to look a gift horse in the mouth, they mean that you should not criticize or feel doubt about something good that has been offered to you

Don't ask how the sausage is made.
This phrase stems from the fact that sausage is often made from the less desirable parts of an animal. Even though it may taste delicious, you may not want to think about putting a tube of pig anus in your mouth. Just enjoy the finished product, and don't dwell too much on its origins.
"The ends justify the means." - This is dark, and generally considered negative, but it basically means if the final result is good, it doesn't matter how you got there.
"You can't make an omelet without breaking a few eggs." - Again, somewhat negative it tone, but keeps the food reference.
