1. Prepare Your Walnuts: Start with whole walnuts that are still in their tough shells.
2. Boil a Pot of Water: Bring a large pot of water to a rolling boil.
3. Add the Walnuts: Carefully place the whole walnuts into the boiling water, ensuring they are fully submerged.
4. Boil for 5 Minutes: Allow the walnuts to boil for just 5 minutes. This brief boiling time is sufficient to soften the shells.
5. Remove and Cool: Using a slotted spoon or tongs, carefully take the walnuts out of the boiling water. Place them on a tray or a clean towel to cool until they are comfortable to handle.
6. Crack Open with Ease: Thanks to the brief boiling, you’ll find it significantly easier to crack open the softened walnut shells. You can use a nutcracker or a specialized tool for this purpose. Alternatively, you can gently apply pressure with your hands to crack the shells.
7. Utilize the Nutmeat: Once the nutmeat is extracted, you can use it in a wide range of culinary creations. Walnut kernels are versatile and can be added to both savory and sweet dishes, such as salads, stir-fries, cakes, and brownies.

The key to the success of this method is the expansion of moisture within the shells caused by the heat, which makes them more pliable and easier to crack open. Boiling whole walnuts in already boiling water is a time-tested technique that simplifies the process of enjoying these delicious nuts and is a testament to the culinary wisdom passed down through generations.
