Place raw cream in a bowl. Add one sachet of starter and mix well with a whisk.

Pour the cream into a mason jar and cover with a kitchen cloth or cheesecloth with a rubber band. Leave in a warm, dark place for at least 12 hours undisturbed or until it is set and tastes sour.Pro tip – we want the active culture in the milk to breathe and multiply so cover but do not seal. Place in the fridge for at least 3 hours before you use it. This SC will keep in the fridge for up to 3 weeks.
Tips for Success
Use Fresh Ingredients: Use fresh, high-quality cream and starter ingredients (buttermilk, sour cream, yogurt, lemon juice, or vinegar) for the best results. Use Clean Equipment: Make sure all utensils, jars, and containers are clean and sanitized to prevent the growth of harmful bacteria. Maintain Consistent Temperature: Keep the mixture at a consistent room temperature (around 70°F/21°C) during the fermentation process for optimal results. Cover Loosely: Cover the jar loosely with a clean cloth or paper towel to allow air circulation while protecting the mixture from dust and contaminants. Check for Thickness: Check the SC after 12 hours and continue fermenting until it reaches the desired thickness. It may take up to 24 hours or longer depending on the method and conditions. Stir Well: Stir the SC well before refrigerating to ensure a smooth and consistent texture. Refrigerate Before Use: Refrigerate the SC for a few hours before using to chill and thicken further. Use Within a Week: Homemade SC is best consumed within a week of making for optimal freshness and flavor.
Troubleshooting
Not Thickening: If the SC is not thickening after the fermentation period, it may be due to low room temperature or using ultra-pasteurized cream. Try placing the mixture in a warmer spot or using cream that is not ultra-pasteurized. Unpleasant Smell: If the SC has an unpleasant smell, it may be due to contamination or using expired cream. Make sure all equipment is clean and sanitized, and use fresh cream. Too Thin: If the SC is too thin, it may not have been cultured for long enough. Allow it to ferment for a longer period, checking for thickness periodically. Not Tangy Enough: If the SC is not tangy enough, it may not have fermented long enough. Allow it to ferment for a longer period to develop a tangier flavor. Separation: If the SC separates into liquid and solids, it may be due to over-stirring or using cream with too high of a fat content. Stir gently and use a lower-fat cream if possible. Grainy Texture: If the SC has a grainy texture, it may be due to using cold cream or over-stirring. Allow the cream to come to room temperature before mixing, and stir gently. Mold: If mold develops on the surface of the SC, discard it immediately. This can occur if the cream was not properly sanitized or if it was contaminated during the fermentation process.
