Frequently Asked Questions

Does Flour Expire?

Yes, flour does expire. Shelf life depends on the specific flour type, so check the ”best before date” on the package. Optimal flour storage is in an airtight container, placed in a dark, dry, cool area. Avoid storage in the freezer or refrigerator, as moisture can seep into the flour and affect baking outcomes. Cup4Cup flour blends, if stored properly, will not expire for approximately one year, though we recommend deferring to the “best before date” that is printed on the packaging.

How to make almond flour?

Start with 1 cup of raw or blanched almonds, sliced or slivered are best since they are precut.  For best results, be sure that your blender or food processor blades are very sharp. To make almond flour, place the raw almonds in the blender or food processor and pulse gently, turning the motor on and off frequently, until the almonds are pulverized. Do not grind the nuts with the motor running continuously or it will turn the almonds into an oily paste. Store the almond flour in an airtight container in a cool and dark and dry place or in the freezer.

Bread flour is a high-gluten flour derived form hard wheat with a protein content of about 13-14%.

What is Cake Flour?

Cake flour is a bleached, finely-milled wheat flour with a protein content of about 8-10%. It has a lower protein content than all-purpose flour, which is about 10-11% protein. The lower protein provides a softer and lighter texture, making the flour suitable for use in cakes. The bleaching of the cake flour provides fuller, more controlled structure by allowing the flour molecules to bind more effectively with fats, repel liquids and retain gas bubbles produced by leavening agents.

What is Coconut Flour?

Coconut flour is a powdery baking agent that is made of ground dried coconut solids that remain in the coconut after the coconut meat is removed to produce coconut milk. It is gluten free but is not the easiest 1:1 substitute because of its strong moisture absorption that can result in very dry baked goods. Substituting coconut flour will take some additional care.

Made from finely ground cornmeal, corn flour is powdery flour that comes in yellow and white.  It is commonly used for breading with other flours in baking.  Corn flour is also known as cornstarch in Britain and Australia, but not in the USA.

A gluten free diet is one that excludes gluten. Gluten is a protein that is found in wheat and related grains like barley, rye, spelt and titricale. A gluten free diet is used to treat celiac disease, non-celiac gluten sensitivity and sometimes wheat allergy. Celiac disease is caused by an abnormal immune response to gluten which causes inflammation in the small intestines and can prevent essential nutrients from being absorbed. Therefore, for people with celiac disease, eating a gluten free diet helps control the symptoms and complications of celiac disease.

Pastry flour is a finely-milled, soft wheat flour containing higher levels of starch and lower levels of protein than all-purpose flour. With a protein content of about 9%, it contains more protein than cake flour (typically around 8%) and less protein than all-purpose flour (typically between 10-11%). Like cake flour, its low protein content softens and lightens the texture of pastries and other baked goods. Pastry flour can be used to make scones, tarts, cookies, cakes, muffins and even gnocchi.

How is the new Wholesome Flour different from the Cup4Cup Original Flour? Does it perform the same?

Wholesome Cup4Cup is heartier and healthier than our Cup4Cup Original Flour.  Wholesome Cup4Cup contains natural sources of fiber, whole grains, omega-3s and antioxidants which are contributed by the brown rice, flaxseeds and rice bran in the blend. Wholesome Cup4Cup flour’s taste, texture and performance are similar to whole wheat flour, resulting in hearty, nutritious, and denser baked items. You may use it cup-for-cup for regular flour in any recipe. However, due to the high fiber content, recipes may need to be adjusted slightly by adding a bit more liquid or fat, just like you would adjust recipes made with whole wheat flour.

Can I make bread with the Cup4Cup Original Flour?

The Cup4Cup Original blend is most similar in composition to all-purpose or pastry flour, making it suitable as a replacement for regular flour in recipes for cakes, cookies, muffins, pies, biscuits, quick breads, sauces, in pasta dough and as a coating for frying. We do not recommend Cup4Cup as a gluten-free flour replacement in bread recipes that require yeast. This is because Cup4Cup lacks the structure and composition to mimic the rise and texture of yeast-based wheat breads. With that, making bread with Cup4Cup is not impossible; it’s just that the recipe will require some modifications and experimentation. For example, we have been able to modify a brioche recipe and develop Brioche Rolls using Cup4Cup. If you would like the recipe for our Brioche Rolls please visit our Recipe section.
