Your Go-To Guide for a Perfect Sour Cream Substitute

👩‍🍳 Instructions

1. 1

   In a clean glass jar or bowl, combine the heavy cream and lemon juice (or white vinegar). Stir well to ensure the acid is evenly distributed.
2. 2

   Cover the jar loosely with a lid, plastic wrap, or cheesecloth. This allows air to circulate while protecting the mixture.
3. 3

   Let the mixture sit at room temperature (ideally between 68-75°F / 20-24°C) for 24 to 48 hours. The cream will thicken and develop a tangy flavor as it ferments. The warmer your kitchen, the faster this process will occur.
4. 4

   After 24-48 hours, check the consistency and taste. It should be noticeably thicker and have a pleasant tangy flavor, similar to store-bought sour cream. If it's not tangy enough for your liking, let it sit for a few more hours.
5. 5

   Once desired thickness and tang are achieved, stir the homemade sour cream well. It may have a slightly lumpy appearance before stirring.
6. 6

   Transfer to an airtight container and refrigerate. The sour cream will continue to thicken slightly in the refrigerator.
