How to Activate Cashews for Enhanced Digestion and Flavour

Research suggests that soaking nuts can reduce anti-nutrients like phytic acid, potentially enhancing nutrient bioavailability and digestibility. Learning how to activate cashews involves a simple process of soaking and dehydrating that can unlock their full potential, resulting in a creamier texture and richer flavor for your recipes.

Quick Summary

Activating cashews involves soaking them in a saltwater solution to soften the texture and break down anti-nutrients, followed by low-temperature drying to restore their signature crunch.

Key Points

• Soak for 3-6 Hours: Cashews only need a short soaking time to soften and reduce anti-nutrients; over-soaking can make them slimy.

• Add Salt to Soaking Water: A pinch of salt helps neutralize enzyme inhibitors and phytic acid more effectively during the soaking process.

• Rinse Thoroughly After Soaking: This washes away the released phytic acid and other compounds, which should always be discarded.

• Dehydrate at Low Temperature: Use a dehydrator or an oven on its lowest setting (below 65°C) to dry the cashews without destroying heat-sensitive nutrients.

• Ensure Complete Dryness: Store cashews in an airtight container only after they are fully dry to prevent mold growth and preserve crispness.

• Achieve Creamier Textures: Soaked cashews are ideal for making exceptionally smooth nut butters, milks, and dairy-free sauces.

What Does it Mean to Activate Cashews?

Activating cashews is a traditional preparation method that mimics the natural germination process. Raw nuts are in a dormant state, containing protective compounds called enzyme inhibitors and phytic acid. In nature, these compounds prevent premature sprouting. For humans, however, they can interfere with digestion and mineral absorption. The activation process, which involves soaking and dehydrating, helps neutralize these compounds, making the nuts easier to digest and their nutrients more readily available. This process also transforms the texture, making them creamier when wet and crispier when dry, and often results in a sweeter, less bitter taste.

Why You Should Consider Activating Your Cashews

While the human body can typically tolerate anti-nutrients in small amounts, activating nuts can be particularly beneficial for some individuals.

• Improved Digestibility: Soaking breaks down enzyme inhibitors, which can reduce bloating and digestive discomfort often associated with eating raw nuts. For those with sensitive stomachs or conditions like IBS, this can make a significant difference.
• Enhanced Nutrient Absorption: Phytic acid, which binds to minerals like iron, zinc, calcium, and magnesium, is partially neutralized during activation. This potentially frees up these minerals, allowing the body to absorb and utilize them more effectively.
• Superior Texture and Flavor: For culinary purposes, activation is a game-changer. Soaked cashews become incredibly soft, making them the perfect base for silky-smooth vegan creams, cheeses, and sauces. When dehydrated, they become exceptionally crisp and crunchy, unlike the softer texture of many roasted cashews.
• Reduced FODMAP Content: According to Monash University, activating cashews can reduce their FODMAP content, making them a suitable option for those following a low-FODMAP diet.

A Step-by-Step Guide on How to Activate Cashews

Activating cashews at home is a simple process that requires just a little patience and a few basic items. Unlike harder nuts like almonds, cashews require a much shorter soaking time to prevent them from becoming slimy.

Step 1: The Soak

1. Gather ingredients: You will need raw, unroasted cashews, filtered water, and a high-quality salt (like Himalayan pink salt or coarse sea salt).
2. Combine: Place your desired amount of cashews into a large glass or ceramic bowl. Cover them with enough filtered water to submerge them completely, plus an extra inch or two as they will expand.
3. Add salt: Stir in a small amount of salt—about 1 teaspoon of salt per 2 cups of nuts. The salt helps activate the phytase enzyme and aids in breaking down the enzyme inhibitors.
4. Soak time: Let the cashews soak at room temperature for 3 to 6 hours. Unlike other nuts, cashews can turn slimy and taste off if soaked for too long, so keep a close eye on them.

Step 2: Rinse and Dry

1. Drain and rinse: After the soaking period, drain the cashews in a colander. Rinse them thoroughly under running water to wash away the phytic acid and other compounds that have leached out. Discard the soaking water.
2. Prepare for drying: Spread the rinsed cashews in a single, even layer on a dehydrator tray or a baking sheet lined with parchment paper. Avoid overcrowding the tray to ensure even drying.
3. Dehydrate (low heat):
   • Dehydrator: Set the dehydrator to a low temperature (around 45–60°C or 115–140°F) and dry for approximately 12–15 hours.
   • Oven: If using an oven, set it to the lowest possible temperature (preferably no more than 65°C or 150°F) and keep the door slightly ajar to allow moisture to escape. Bake for 12–15 hours, stirring occasionally.
4. Check for dryness: The cashews are ready when they are completely dry and crunchy. They will become crispier as they cool. If they are still soft, continue drying. Any remaining moisture can lead to mold.

Step 3: Storage

Once fully cooled, store your activated cashews in an airtight container in a cool, dark place. For longer-term storage, they can be kept in the refrigerator or freezer to maintain freshness.
