This Vegan Sour Cream Recipe requires just 5 ingredients and comes together easily. It's so rich, tangy, and creamy that you'll want to dollop it on everything!
Drain and rinse the cashews. Discard soaking water.
Add all the ingredients to a high-powered blender (starting with the yogurt and lemon juice). Blend on high until creamy and smooth. This could take a few minutes. Scrape down sides as needed. Taste to see if it needs more lemon, salt or vinegar.
Pour into an airtight container in the fridge for 1-2 hours to firm it up. It will keep about 4-5 days.
Notes
If you're unsure how salty or tangy you want the sour cream to be, it's best to use less lemon, vinegar and salt to start. You can always taste and add more after blending.
I get a perfect consistency every time with the listed ingredient amounts. However, If you feel your sour cream is too thick, you can add a few teaspoons of unsweetened non-dairy milk, yogurt or water to thin it out. Add more as needed but only a small amount at a time to avoid a runny consistency.
If you don't have a high-speed blender, the sour cream may not get smooth enough.
Some non-dairy yogurt brands have an off-white color, which will make your sour cream slightly off-white. It won't affect the tastiness though. I prefer So Delicious for its color and thickness.
I leave the cashews in the fridge while they are soaking.
Prep time doesn't include soaking time.
Yields about 1 cup.
If you have lactic acid, you can use that in replace of the lemon juice. It adds a similar tangy flavor that cultured cheese has. I usually add 1 ¼ teaspoons. You may need to add a few teaspoons of water or non-dairy milk to make up the liquid portion of the lemon juice. Blend first and then decide.
The cashews must soak for a minimum of 4-6 hours, or they will produce gritty results.
