A note from the author, gluten-free chef Judy Haubert: "Successfully adapting ratios and measurements for gluten-free baked goods can be tricky and more than a little frustrating. If you've done any gluten-free baking, you've probably heard the heated debate between weighing vs. measuring GF flours. When testing my gluten-free recipes, I always do both, but I realize that not all home cooks have easy access to a scale. I've come up with a method that ensures that my measured ingredients consistently weigh the same for each recipe repetition. I call it "Scoop, Shake & Level," referring to using your measuring cup to first scoop out the flour (versus spooning or even pouring it into the measuring cup), giving the cup a little shake to settle the ingredient slightly, then using a flat-edged instrument to level off the flour across the top of the measuring cup. I've done this countless times, with the weight always accurate down to several grams. I'm not sure how this method holds up with anyone else's GF recipes, but I feel I can vouch for it for my own."
