I love King Arthur Flour. They stock the best cooking equipment, and their flours are high quality and reliable. I also have a Pavlovian response to their cinnamon buns.
But… my appreciation is deepened every time I find valuable resources – tiny treasures for bakers – hidden in their website. Today, it was a table of how to thicken fruits for pie using flour, corn starch, tapioca, sure gel, and their branded “Pie Filling Enhancer.”
King Arthur Flour has this super-useful chart on their website to convert volume to weight. Importantly, their flours have different weights for a 1 cup volume, and you can find that specific info at this page.
I can’t say enough about baking by weight. It’s always difficult for me to bake by volume anymore – I hate sifting dry ingredients and, when it matters, I don’t want to skip the step and have overly dry baked goods. I still turn to the tablespoons and teaspoons for things like vanilla, salt, or baking powder/soda but everything else – give me weight to give me cake!
