Bring a pot of water to a rolling boil. Add the walnut halves and baking soda, stirring gently to combine. Let the walnuts boil for 2–3 minutes to remove bitterness.

Using a slotted spoon, remove the walnuts and rinse them under clean water 2–3 times to wash away any baking soda residue.

Bring a fresh pot of water to a boil and add the rinsed walnuts. Boil again for 2 minutes, then drain thoroughly. Make sure there is no excess water left on the surface, as moisture can prevent the coating from sticking evenly.

Transfer the drained walnuts to a large bowl. Add the Granulated Sugar, honey, and sesame seeds.

Mix thoroughly using chopsticks or a silicone spatula until every walnut is evenly coated with the honey-sugar mixture and sesame seeds.

Oven Method

Preheat the oven to 150°C (300°F). Line a baking tray with parchment paper and spread the walnuts out in a single, even layer, making sure they don't overlap.

Bake for 30 minutes. Halfway through baking, remove the tray and gently flip the walnuts to ensure even crisping.

Once baked, remove from the oven and allow the walnuts to cool completely in a well-ventilated area. They will firm up and crisp further as they cool.

Air Fryer Method

Line the air fryer basket with parchment paper and spread the walnuts in a single layer.

Set the air fryer to 160°C (320°F) and cook for 20 minutes. Halfway through cooking, pull out the basket and gently flip the walnuts for even browning.

Remove and let cool completely. The walnuts will become fully crisp once cooled.

Once completely cooled, transfer the candied walnuts to an airtight container. Store in a cool, dry place to keep them crisp and prevent moisture absorption. They're perfect for snacking anytime.
