The Food Lab: What Apples Are Best for Apple Pie?
Experimental Food Science (like chemistry lab for Home Economics Majors) was doing labs like this. Too bad this type of class is hard to find, these days in the USA. All About Apples by seriouseats: Which are best for pies and which turn brown the least. #Apples #Pie #Brown
Have always used Granny Smith and Braeburn in my pies. The taste and texture is incredible. Also, I reserve some if the juice from apple, sugar mixture and brush on the top crust. Result is beautiful golden color and the apple flavor in the crust as well.
What a great insight! Thank you!
