California walnuts take on a new role as a savory, plant-based component with depth, texture, and visual appeal. Toasted walnuts, finely chopped and combined with mushrooms, create a balanced foundation that delivers richness, moisture, and a satisfying chew. Aromatics such as lemongrass, garlic, and ginger build layered flavor, while optional annatto oil imparts a deep, natural color and subtle earthiness. This flavorful walnut meat serves as a versatile base for globally inspired wraps, rolls, bowls, fillings, and composed dishes.
3 cups (8 oz or 265 g) California walnuts
2 cups (6 oz or 175 g) Sliced button mushrooms
2 Tbsp (1 oz or 30 g) Vegetable oil (or annatto oil, see Chef Tips below)
¼ tsp (2 g) Kosher salt
½ tsp (3 g) Ground black pepper
1 cup (8 oz or 240 g) Water
¼ cup (1 oz or 30 g) Minced lemongrass
1 Tbsp (7 g) Minced garlic
1 Tbsp (7 g) Minced ginger
1 Tbsp (½ oz or 15 g) Soy sauce and/or fish sauce
1 Tbsp (½ oz or 15 g) Grated palm sugar or light brown sugar
Preheat oven to 350°F (170°C).
On a parchment-lined sheet tray, spread walnuts in a single layer and roast in the oven for 8-10 minutes or until beginning to brown. Allow walnuts to cool to room temperature before processing.
Transfer the walnuts to a food processor bowl and pulse until they are ground to a very fine texture, yet still coarsely chopped and not a fine meal or paste. Remove and reserve.
Place the mushrooms in the same food processor bowl and pulse until very finely ground, similar to, if not slightly larger than, walnuts.
Combine the processed walnuts and mushrooms in a bowl until the ingredients are evenly distributed.
Heat a 12-inch non-stick sauté pan over medium heat, then add the vegetable oil (or optional annatto oil) to the pan.
Add the mushroom-walnut mixture to the pan. Add salt and pepper. Then add water and mix well.
Cook the mixture for about 5 minutes, stirring frequently, until the moisture evaporates and the mixture is somewhat dry.
Stir in lemongrass, garlic, ginger, soy, or fish sauce, mixing very well to make sure the seasoning is well distributed.
Keep cooking until the mixture begins to brown. Taste and adjust the seasoning as needed. If you want a more tender walnut meat, add additional water in ¼ cup increments and cook until absorbed, repeating until achieving the desired texture.
For a more vibrant colored walnut meat mixture, use the optional annatto oil. Simmer ¼ cup (1 oz or 28 g) annatto seeds in ½ cup (4 oz or 120 g) of neutral oil until they begin to sizzle. Remove from heat, let steep until cool, then strain. Use this vibrant oil to infuse both color and flavor into the walnut mixture.
