### Tuesday Tricks and Tips

When dealing with Gluten Free flours, you have to realize one vital thing. You HAVE to weigh things. They will never turn out the same if you use a cup or what have you. In addition, GF flours have different weights per equiviliant cups. So when you  convert, you have to additionally convert into the separate weights needed. If you look up my cake recipe, you'll see this is how I converted the cake flour into gluten free once I'd decided my percentages. Here's some weights.

Evil Cake Flour is 100grams per cup
Evil Bread Flour is 136grams per cup
Evil AP Flour is 127grams per cup

However

Almond Flour/Meal is 112 grams per cup
Potato Starch is 170 grams per cup
Rice Flour is 158 grams per cup

That's a lot of variations, ain't it?

So what you do is when you've decided on percentage you want of each to substitute. So if you have a recipe that calls for 2 2/3  cups of Cake Flour, that translates to 266.6 or 267grams of Cake Flour. If you decide on a 60/40 split between protein and starch. That would mean for example : 267*.60= 160 grams of Protein and 107grams of Starch. However, because GF flours have a different density, you then have to multiple those weights by the density of the GF flours. In this example, that would be 160x 1.12 = 179.4grams of protein and 181.56grams of starch.  Equally a total weight of 360 grams.

(Amount in cups) x (Weight of type of Flour called for in recipe) = Amount in grams
(Amount in grams/Percentage in Starches) + (Amount in grams/Percentage of Starches)= Amount in grams
(Grams in category (proteins/starches/etc) x (Weight of GF alternative per cup) = Amount of GF alternative needed
