Dairy-Free Sour Cream

A thick, tangy dairy-free sour cream made from soaked cashews, lemon juice, apple cider vinegar, and salt. It takes about 10 minutes of hands-on work, but needs soaking and chilling time to become smooth, cold, and spoonable.

Ingredients

Base

1 cupRaw cashews
2 cupsBoiling water, for soaking

Blend

½ cupCold water
1½ tbspFresh lemon juice
2 tspApple cider vinegar
¾ tspFine salt
¼ tspDijon mustard
1 tbspNeutral oil, optional for extra richness

Cultured Variation

1 capsuleProbiotic capsule, optional for cultured variation
1 tbspPlain unsweetened dairy-free yogurt with live cultures, optional alternative to probiotic
1 tbspRaw sauerkraut brine, optional alternative culture starter

Instructions

1
Place the cashews in a heatproof bowl and cover with the boiling water. Let soak for 30 minutes, then drain and rinse. If your blender is not high-speed, soak the cashews for 1 hour so the sour cream blends smoother.
2
Add the drained cashews, cold water, lemon juice, apple cider vinegar, salt, Dijon mustard, and neutral oil if using to a blender.
3
Blend on high for 1 to 2 minutes, stopping to scrape down the sides as needed, until completely smooth. The mixture should look glossy and thick, with no graininess.
4
Taste and adjust carefully. Add more lemon juice 1 teaspoon at a time for brightness, more vinegar 1 teaspoon at a time for sharper tang, or a pinch more salt if it tastes flat. The quick version should taste tangy but not mouth-puckering.
5
For a spoonable topping, transfer to a jar and chill for at least 1 hour. It will thicken as it cools. For a drizzle, whisk in cold water 1 tablespoon at a time until it reaches the texture you want.
6
For the cultured variation, blend the cashews with the cold water and either the powder from 1 probiotic capsule, 1 tablespoon plain unsweetened dairy-free yogurt with live cultures, or 1 tablespoon raw sauerkraut brine. Leave out the lemon juice, vinegar, salt, Dijon, and oil at first. Transfer to a very clean jar, cover loosely, and let sit at cool room temperature for 12 to 24 hours, until lightly tangy. Then stir or blend in the lemon juice, vinegar, salt, Dijon, and oil. Chill before serving.
7
Store covered in the refrigerator for up to 5 days. Stir before using; if it thickens too much, loosen with a small splash of water or lemon juice. If the cultured version ever smells unpleasant, grows mold, or turns pink or fuzzy, discard it.

Dairy Substitutions Used

Traditional sour cream is replaced with soaked raw cashews blended into a thick cream. Lemon juice and apple cider vinegar provide quick brightness, while the optional cultured variation uses live cultures from a probiotic capsule, plain dairy-free yogurt, or raw sauerkraut brine to create a deeper, more authentic tang. Salt and a tiny amount of Dijon round out the flavor so it tastes savory rather than like plain cashew cream.

Tips & Variations

Timing note: This is about 10 minutes of hands-on work, but the real path to a spoonable result is 30 minutes of soaking, a few minutes of blending and adjusting, and at least 1 hour of chilling. Plan on about 1 hour 40 minutes total for the quick version.

Use raw cashews: Roasted cashews taste too nutty here and can make the sour cream darker and heavier. Raw cashews blend cleaner and taste more neutral.

Chill before judging thickness: The sour cream may look a little loose straight from the blender, but it firms up noticeably after an hour in the refrigerator.

Quick versus cultured: The quick version is best when you need sour cream today. The cultured version tastes rounder and more like traditional sour cream, with less sharp lemon-vinegar bite.

Culture safely: Use a clean jar and keep the cultured version at cool room temperature, not in a hot kitchen. Start checking after 12 hours and refrigerate once it tastes pleasantly tangy.

Sauerkraut brine note: Use brine from raw, refrigerated, unpasteurized sauerkraut. Pasteurized shelf-stable brine can add acidity but will not reliably culture the sour cream. Because sauerkraut brine is salty and assertive, start with just 1 tablespoon.

For tacos and crunchwraps: Use it thick and cold, or stir in a little lime juice and hot sauce for a quick spicy sour cream.

For baked potatoes: Keep it thick, then top with chives, black pepper, and a tiny drizzle of olive oil if you want a richer finish.

For dressings: Thin with water until pourable, then add herbs, garlic powder, onion powder, or pickle brine depending on the dressing you are making.

Nut-free tofu option: Drain 12 ounces of silken tofu in a fine-mesh strainer or on paper towels for 10 minutes, then blend it with the lemon juice, vinegar, Dijon, 1 tablespoon neutral oil, and 1 teaspoon fine salt, skipping the cashews and soaking water. The flavor is lighter and less rich than the cashew version, but the oil and extra salt help it taste fuller and less watery.

Avoid sweetened yogurt: If you ever mix this with dairy-free yogurt for extra tang, make sure the yogurt is plain and unsweetened. Vanilla or sweetened yogurt will ruin the savory flavor.
