Daisy sour cream is a quick, creamy condiment that brightens everything from tacos to baked potatoes. This recipe delivers a tangy, thick sour cream with a hint of lemon and salt, ready in just 10 minutes. It’s a versatile staple that works as a topping, dip, or baking ingredient, and it tastes fresher than store-bought versions.
Ingredients
- 2 cups (480 ml) heavy cream (or 1 cup heavy cream + 1 cup buttermilk for a lighter version)
- 2 tablespoons (30 ml) fresh lemon juice
- 1/2 teaspoon salt (optional, to taste)
- 1/4 cup (60 ml) whole milk (optional, for thinning)
Instructions
- In a clean glass bowl or jar, combine the heavy cream and lemon juice. Stir gently with a spoon or whisk for about 30 seconds—do not overmix.
- Cover the bowl with a clean kitchen towel or plastic wrap and let it sit at room temperature (70°F/21°C) for 24 hours. The mixture will thicken and become tangy as the acid works on the cream.
- After 24 hours, stir in the salt (if using). The sour cream should be thick and spreadable. If it’s too thick for your liking, whisk in the milk a tablespoon at a time until it reaches the desired consistency.
- Transfer to an airtight container and refrigerate for at least 2 hours before serving. The flavor deepens as it chills.
Tips
- Substitution: If you don’t have heavy cream, you can use 1 cup (240 ml) whole milk and 1 cup (240 ml) plain yogurt, but the result will be thinner and less rich. For a dairy-free version, use full-fat coconut cream and lemon juice—it will taste slightly coconutty.
- Storage: Keep homemade sour cream in a sealed container in the fridge for up to 2 weeks. Stir before use, as some separation is normal.
- Common mistake: Overmixing or using ultra-pasteurized cream can prevent thickening. If your cream doesn’t thicken after 24 hours, add 1 tablespoon of buttermilk and let it sit another 12 hours.
- Flavor boost: Add a pinch of sugar or a dash of white vinegar to enhance tanginess without extra lemon flavor.
Serving Suggestions
Use daisy sour cream as a topping for baked potatoes, chili, tacos, or nachos. It also works as a base for dips—mix with ranch seasoning, chives, or garlic powder. For a breakfast twist, dollop it on pancakes or waffles with fresh berries.
Variations
- Herbed Sour Cream: Stir in 1 tablespoon of chopped fresh dill, parsley, or chives before chilling.
- Spicy Sour Cream: Add 1 teaspoon of hot sauce or 1/2 teaspoon of cayenne pepper for a kick.
- Sweet Sour Cream: Omit the salt and add 2 tablespoons of honey or maple syrup for a dessert-friendly version.
- Onion Sour Cream: Mix in 1/4 cup (40 g) finely minced shallots or green onions for a savory spread.
Storage and Reheating
Store daisy sour cream in an airtight container in the refrigerator for up to 2 weeks. Do not freeze, as the texture will become grainy and watery upon thawing. If you must freeze, use it only in cooked dishes like soups or casseroles, and expect a change in texture. Reheating is not recommended—serve cold or at room temperature. If you prefer a warm topping, stir it into hot dishes just before serving, but do not boil it or it will curdle.
Frequently Asked Questions
Can I use half-and-half instead of heavy cream? Yes, but the sour cream will be thinner. To compensate, reduce the lemon juice to 1 tablespoon and add 1 teaspoon of unflavored gelatin dissolved in 2 tablespoons of water to help thicken.
Why didn’t my sour cream thicken? This usually happens if the cream was ultra-pasteurized (which resists thickening) or if the room was too cool. Move it to a warmer spot (around 75°F/24°C) and add a splash of buttermilk or yogurt to introduce more lactic acid bacteria.
Is this safe to eat after sitting out for 24 hours? Yes, because the acid from the lemon juice lowers the pH, creating an environment that inhibits harmful bacteria. However, always use fresh cream and clean utensils. If you see mold or an off smell, discard it.
Can I make this without lemon juice? Yes, use 2 tablespoons of white vinegar or apple cider vinegar instead. The flavor will be slightly different but still tangy.
How long does homemade sour cream last? Properly stored, it stays fresh for up to 2 weeks in the fridge. Always check for signs of spoilage like discoloration or a yeasty smell.
Can I use this in baking? Absolutely. Substitute it 1:1 for store-bought sour cream in cakes, muffins, or quick breads. The higher fat content may make baked goods slightly richer.
