If your powdered food is less clumpy and more powdery, it may be difficult to transfer it to your blender/processor. In this case, use a funnel to prevent spilling good powder. Use a tool, like a normal or wooden spoon, to guide your powdered food into the blender/processor from its container.

Powdered food that is very lumpy might benefit from a lower speed setting, first. On some blenders/processors, this might be indicated as the “Stir” function. Your powdered food shouldn’t require more than a short time at a medium speed to refine it back to its original, lumpless form. It is generally recommended, when using a blender/processor, to keep a hand on its top when running to prevent it coming loose. [1] X Research source

The cold temperatures in your freezer will create a dry environment for your stored powdered food and reduce the formation of lumps.

The temperature of the ingredients you use can influence the outcome of your recipe. If you’re concerned the temperature of your powdered food might affect the outcome, it may be best to allow your ingredients to sit until they are room temperature. [2] X Research source

Try to get the lumps in your food as small as possible. Aim to have no chunks larger than roughly the size of a marble. This will make the straining process easier on you.

Try not to be too forceful when pushing lumps through the strainer. This could cause damage to the strainer. Some lumps may not break apart easily. In many cases, these will be unsalvageable and can be thrown away. Tiny lumps that are small enough to fit through the spaces of your sturdy strainer may remain in the mixture. This is ok. You may need to sift with your sturdy strainer a few times before your powdered food becomes consistent throughout. When you reach this point, you’re ready to move on.

Fine mesh strainers are usually a little more delicate than the thicker variety you used previously. Use light to moderate force to prevent breaking your strainer. If you notice lumps that stubbornly resist breaking up in your strainer, you should remove these and throw them away. You may need to strain your powdered food several times in your fine mesh strainer before it is consistent throughout and your lumps are broken up. Depending on how find your mesh strainer is, you may have very small lumps remaining in your powdered food. In this case, you can repeat the process with an even finer mesh strainer until all lumps are gone.

While rice and beans are common moisture absorbers, many other things might be used, like unpopped popcorn. [4] X Research source

If your powdered food has not started lumping yet, simply passing it through a fine mesh strainer and into a fresh, dry, airtight container should help keep it lumpless.

To prevent this from happening, you may want to first put your food powder in your hand or a spoon and then sprinkle it onto the food you are preparing. [6] X Research source
