Step 1

Place the cashews in a bowl and cover them with water. Soak for 1 hour (or the very least, 30 minutes if you have a high speed blender). For preparation in advance, you can soak the cashews overnight, which is even better.

Step 2

Juice the limes.

Step 3

Drain the cashews. Add the cashews, water, lime juice, cilantro, and kosher salt to a blender, then blend on high for 1 minute. Stop and scrape, then add additional liquid if necessary to come to the desired creamy consistency (we added 2 additional tablespoons; you could add more for a more drizzle-able sauce). Blend for several minutes until creamy and smooth. Store in a sealed container in the refrigerator for up to 1 week or in the freezer for several months.
