Frequently Asked Questions
Q: Can I use a different type of nut instead of cashews?
A: Yes, you can substitute raw cashews with macadamia nuts or blanched almonds. However, cashews provide the creamiest texture due to their natural fat content. If using almonds, ensure they are blanched and soaked longer for a smoother consistency.
Q: What if I don’t have nutritional yeast? Can I omit it?
A: Yes, nutritional yeast is optional and primarily adds a subtle cheesy flavor. If you don’t have it, you can leave it out or substitute with a pinch of grated vegan Parmesan or even a small amount of miso paste for added umami.
Q: How do I store leftovers, and how long will it keep?
A: Store the sauce in an airtight container in the refrigerator for up to 4-5 days. Before reheating, you may need to add a splash of plant-based milk or water to loosen the sauce, as it tends to thicken when chilled.
Q: Can I freeze this sauce for later use?
A: Yes, this sauce freezes well. Store it in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight and re-blend or whisk with a bit of plant-based milk to restore its creamy texture before reheating.
Q: What can I use instead of almond milk?
A: You can substitute almond milk with any other unsweetened plant-based milk, such as oat milk, soy milk, or cashew milk. Avoid sweetened or flavored varieties, as they may alter the taste of the sauce.
Q: My sauce tastes too tangy. How can I fix it?
A: If the lemon flavor is too strong, balance it out by adding a small pinch of sugar or a little more nutritional yeast for richness. You can also add an extra tablespoon of plant-based milk to mellow the tanginess.
Q: What are some ways to serve this sauce?
A: This sauce is incredibly versatile. Serve it over your favorite pasta, drizzle it over roasted vegetables, use it as a creamy dip for bread or crackers, or even as a sauce for pizza or grain bowls. For a protein boost, pair it with grilled tofu or chickpeas.
