California walnut cold foam is a creamy, and light, and plant-based topping that delivers a naturally rich flavor and smooth texture, offering a dairy-free alternative to traditional cold foams. Made with walnuts, optionally leverage skinless walnuts for a lighter color and milder taste, this versatile ingredient can be used across the menu. It adds an indulgent body to cold brew, coffee drinks, iced teas, and dirty sodas, while also bringing a unique texture and flavor boost to both mocktails and cocktails. Creamy walnut cold foam can also be used as a dessert topping or layer, as well as a garnish for soups.
3 cups (13 oz or 350 g) California walnuts
2 ½ cups (21 oz or 600 g) Water, room temperature
½ cup (2 oz or 60 g) Powdered sugar
¼ tsp (1-2 g) Kosher salt
2 tsp (⅓ oz or 10 g) Vanilla extract (optional)
Combine all ingredients in a high-speed blender. Blend at medium-high speed for 3-5 minutes until very smooth, scraping down halfway through.
Cool over an ice bath, transfer to a container, and store in the refrigerator for up to 3-5 days.
Fill a pressurized whipped cream container with the cream as directed by the manufacturer, ensuring the lid is sealed tightly.
Charge the cream with two N₂O (nitrous oxide) chargers, then test its thickness and volume; add more N₂O as needed to reach the desired consistency.
This recipe utilizes a professional blender. This recipe requires a pressurized cream dispenser, sometimes called a whipping siphon or foam canister, charged with an N₂O cartridge
Due to the friction in the blender, the cream will heat up to about 130-140 F/ 55-60 C.
Blend on high speed until completely smooth, allowing the blender to run long enough to fully break down the walnuts. Because this cream is thinner, it blends easily and can be used immediately, but chilling for 12 hours will give it a slightly richer mouthfeel.
