Cashew Milk - what is it

What Is Cashew Milk?

Originating from the tropical cashew fruit, cashew milk is made by blending cashews with water. This process results in a smooth, rich liquid that’s become a staple in vegan and lactose-intolerant communities. It’s a relatively recent addition to the dairy-free market, gaining popularity for its flavor and health benefits.

Nutritional Breakdown of Cashew Milk

Cashew milk is not only delicious but also packed with nutrients. It’s typically lower in calories compared to other nut milks, making it an excellent choice for those of us monitoring our calorie intake.

A cup of unsweetened homemade cashew milk usually contains about 25-50 calories, depending on how many cashews we use. It’s also rich in vitamins and minerals like magnesium, vitamin B6, iron, and calcium, especially if it’s fortified.

Vitamin B60.1 mg
Iron1.89 mg
Calcium20-25 mg (if fortified)
FODMAP foods

Is Cashew Milk Low FODMAP?

When evaluating whether cashew milk is low FODMAP, it’s important to consider its suitability for individuals with dietary sensitivities or irritable bowel syndrome (IBS).

Cashew milk, like almond milk and lactose-free dairy milk, can be regarded as a low FODMAP alternative to regular cow’s milk. This is primarily because it is made by blending cashews with water.

This results in a beverage that doesn’t contain significant amounts of  Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols (FODMAPs), which are the carbohydrates known to trigger digestive discomfort in some people. And unlike cow’s milk, cashew milk is naturally free of lactose, one of the most common FODMAPs in dairy.

That said, it’s important to exercise caution when selecting store-bought cashew milk products, as some may contain additives, sweeteners or thickeners that introduce high FODMAP ingredients. To ensure you’re following a low FODMAP diet, we recommend opting for unsweetened and unflavored versions of cashew milk. Always check product labels meticulously and prioritize products with minimal additives. 

For those following a strict low FODMAP regimen, making homemade cashew milk may be the safest and most tailored option. Making it yourself offers far greater control over ingredients. This allows for a purer, FODMAP-friendly beverage.

If making cashew milk from scratch is something that interests you, you’re in luck. We’ve got you covered later on in this article.

Shelf Life Of Cashew Milk

When unopened, commercial cashew milk has a surprisingly long shelf life. Thanks to the pasteurization and packaging process, it can last anywhere from 6 to 12 months when stored properly.

The key is to keep it in a cool, dry place away from direct sunlight. Always check the expiration date on the package for the best guidance.

Does Unopened Cashew Milk Need To Be Refrigerated?

A common question we encounter is whether unopened cashew milk needs refrigeration. The answer depends on the type of cashew milk we’re talking about. Shelf-stable varieties, found in the non-refrigerated aisles, don’t require refrigeration until after they’re opened. However, refrigerated types of cashew milk must always be kept cold.

How Long Can Cashew Milk Stay Out Of The Fridge?

Once opened, cashew milk’s shelf life reduces significantly. We should consume refrigerated cashew milk within 7-10 days of opening. But how long can it stay out of the fridge? Generally, we shouldn’t leave opened cashew milk at room temperature for more than two hours, as bacteria grow rapidly at temperatures between 40°F and 140°F.

Storing Cashew Milk

Proper storage of cashew milk is crucial for maintaining its quality and extending its shelf life. Whether we’ve picked it off a store shelf or made it at home, knowing the best ways to store cashew milk ensures we always have a fresh and healthy product. Let’s dive into the specifics.

Spin the Food Tip

When refrigerating, store your cashew milk away from strong-smelling foods to prevent flavor absorption. Also place it at the back of the fridge where the temperature is coldest and most stable.

Can You Freeze Cashew Milk?

Yes, you can freeze cashew milk! Freezing cashew milk is a convenient way to extend its shelf life significantly. It also prevents wastage, especially if you have excess or need to use it at a later date.

When freezing cashew milk, it’s crucial to do so in an airtight container or an ice cube tray to prevent the milk from absorbing any unwanted odors from the freezer and to minimize freezer burn. Remember that liquid expands when frozen, so the same rule that applies to freezing smoothies applies here: leave some space in the container to accommodate this expansion.

Thaw frozen cashew milk by placing it in the refrigerator overnight or using the defrost function on your microwave if you need it quickly. However, it’s worth noting that the texture of cashew milk may change slightly after freezing, but it can still be used in cooking, baking, or smoothies without a significant impact on the final result.

Shake or stir the thawed cashew milk to recombine any separated components, and it should be ready for use. Another really effective way to restore consistency in your thawed cashew milk is to throw it in a blender for a quick blitz.

DIY Homemade Cashew Milk

Making cashew milk at home is a simple and rewarding process. Not only does homemade cashew milk taste fresher, but it also allows us to control the ingredients, ensuring a natural and healthy beverage.

Let’s look at how we can make this nutritious drink from scratch and how to store it properly.

How To Make Homemade Cashew Milk From Scratch

Creating our own cashew milk is straightforward. Here’s a quick guide:

How to make homemade cashew milk from scratch

INGREDIENTS

  • 1 cup raw cashews
  • 4 cups water (plus more for soaking)
  • Optional: Sweeteners or flavourings (e.g. vanilla or cinnamon)

INSTRUCTIONS

  • Soak the cashews in water for 4 hours or overnight.
  • Drain and rinse the soaked cashews.
  • Blend cashews with 4 cups of fresh water until smooth.
  • Strain the mixture using a nut milk bag or cheesecloth to remove solids.
  • Add optional sweeteners or flavorings.
  • Store in a clean, airtight container in the refrigerator.
Homemade vs Store-Bought

Homemade cashew milk typically has fewer additives and preservatives than store-bought versions. It’s a healthier option, as we can avoid added sugars and thickeners often found in commercial products. The calorie content can be adjusted by varying the number of cashews used.

How Long Does Homemade Cashew Milk Last?

In the fridge, homemade cashew milk stays fresh for about 4-5 days. Remember, since it lacks preservatives, it doesn’t last as long as store-bought varieties. If you notice any off-smell, taste, or mold, it’s time to discard it. 

Also keep in mind that natural separation tends to occur with cashew milk made from scratch, so always shake well before drinking.

How To Tell If Cashew Milk Is Bad

It’s crucial for us to recognize the signs of spoilage in cashew milk to ensure we consume a safe and healthy product. Whether store-bought or homemade, cashew milk can go bad, and knowing what to look out for is essential. Here’s how we can tell if our cashew milk has spoiled.
