It’s not every day that a new flour arrives in my kitchen. When I received coconut flour for my birthday way back in April, it was an opportunity to play with my food — in the pursuit of good health, good taste, good fun. But, being almost entirely unfamiliar with coconut flour, I had to do quite a bit of research first.
I quickly learned that it can be a finicky ingredient for newcomers. Most baking recipes are designed for wheat flour and other similar grains, therefore you can’t simply substitute coconut flour to achieve the desired, expected results. You can use coconut flour to replace 10% to 30% of wheat or other flour in a recipe; though, there are recipes created specifically for 100% coconut flour.
To tweak a recipe on your own, take note:
+ Coconut flour is highly absorbent, and requires an equal portion of water or other liquid to be added, usually in a 1:1 ratio.
+ On the other hand, because of its propensity to absorb like a dry sponge, liquids in the recipe should be kept to a minimum — using butter or oil will prevent drying out.
+ As a gluten-free (GF) flour, it doesn’t have that stabilizing power and can yield crumbling pastry — generally one egg (or egg substitute) per one ounce of flour combats this.
+ You may need to reduce overall baking time when substituting coconut flour for wheat flours, sometimes by as much as half at the temperature.
Because our pantry wasn’t yet entirely stocked for gluten-free baking when I made these, I altered Elana’s GF double chocolate mocha biscotti recipe to incorporate whole wheat pastry and coconut flours. Both nutritious, whole wheat pastry flour is high in protein and whole grains, low in gluten (not GF), and provides tender results; while coconut flour is high in fiber and protein, is gluten-free, very low in carbohydrates, and has a delicate hint of coconut.
By the time I calculated the percentages and noted all the changes to be made, the two recipes were faintly related. This meant great care and patience at each step to ensure everything came together. In the end, I patted the dough into a large log, put the pan in the oven and crossed my fingers all would go well.
