All-purpose flour is one of the most versatile and widely used varieties of flour. It is classified as medium-grade and is made up of both soft and hard wheat. As a result, it has a somewhat higher protein content than other varieties of flour.

The protein imparts a delightfully frothy and silky texture to baked items. Your all-purpose flour will last between 3 and 8 months if kept in the pantry before opening.

However, if you keep the flour in an airtight container in the refrigerator, it will survive for approximately a year. You may also store your flour in the freezer, where it will keep for up to two years.

After the indicated expiry date, you may keep all-purpose flour for 6 to 8 months. However, you must guarantee that its container or packing is sealed and kept in the refrigerator.

However, it is still safe to use cake flour 6 to 8 months beyond the suggested use date.

4. Whole Wheat Flour

Whole wheat flour is made from unrefined wheat kernels. As such, it contains the kernel’s germ, bran, and endosperm. This flour is coarser in texture than all-purpose flour and includes more fiber and minerals.

It’s ideal for making bread and rolls, but it may also be used in cake and cookie recipes. If you often bake, the easiest way to store whole wheat flour is in a firmly sealed bag or container.

You may put it in the fridge to prolong its life to around 6 months. However, if you store it in a cold, dry area, it should last you around 3 months.

Whole wheat flour may also be frozen and stored in the freezer for up to a year. In the case of whole wheat flour, we do not advocate using it beyond the expiration date.

Almond flour is made by crushing almonds. This makes it a gluten-free and paleo-friendly substitute for wheat flour. It’s also packed in protein and healthy fats, making it a nutritious grain-free choice.

This nut-based flour is finer than other gluten-free flours like coconut flour or tapioca flour. As a result, it is great for baked products such as cookies, cakes, and muffins.
