Ingredients
- Fresh skim or low-fat milk: 4 cups (32 fl oz / 946 ml / 946 g)
- Commercial cultured buttermilk (at room temperature): 0.66 cups (10.6 tbsp / 5.3 fl oz / 160 ml / 160 g)
- Non-instant, non-fat dry milk powder: 0.5 cups (8 tbsp / 2.3 oz / 65 g)
Step-by-Step Instructions
- Pour the 4 cups (32 fl oz / 946 ml / 946 g) of fresh skim or low-fat milk into a heavy-bottomed 2-quart (64 fl oz / 1.9 L) saucepan and place over moderate heat. Stir constantly until the milk reaches exactly 108°F (42°C) on a thermometer, then immediately remove the pan from the heat.
- Place the 0.66 cups (10.6 tbsp / 5.3 fl oz / 160 ml / 160 g) of commercial cultured buttermilk and the 0.5 cups (8 tbsp / 2.3 oz / 65 g) of dry milk powder into a food processor or blender, processing them together for about 15 seconds. While the machine is still running, carefully pour in the warmed milk and process for an additional 15 seconds until completely smooth.
- Immediately pour the blended mixture into a clean 1.5-quart (48 fl oz / 1.4 L) jar, electric yogurt maker, or insulated container, and cover it loosely. Wrap the container securely in a heavy terry towel and set it aside in a warm spot at 70°–80°F (21°–26°C) for 8 to 15 hours until it reaches the firm, luxurious consistency of whipped cream, then tightly cover and refrigerate for up to 1 week.

Pro Tips for the Perfect Set
As a chef, I've made countless batches of cultured dairy, and getting that perfect, thick consistency all comes down to a few critical details. Here are my top tips for nailing this recipe every single time:
- Monitor Your Temperatures Relentlessly: The 108°F (42°C) mark is the sweet spot. If the milk is too hot, it will kill the live bacteria in your starter. If it's too cool, the bacteria will be sluggish, resulting in a runny batch. A reliable digital kitchen thermometer is your best friend here.
- Check Your Starter Culture: When purchasing the commercial cultured buttermilk to use as your starter, look closely at the label. It absolutely must say "contains active cultures" or "live cultures." If the buttermilk has been pasteurized after culturing, the bacteria are dead and your milk will not set.
- Create a Cozy Incubation Spot: If you do not have an electric yogurt maker, you can easily create a warm, draft-free environment. Place your jar inside an unheated oven with just the internal oven light turned on, or set it inside a small cooler alongside a jar of warm water to maintain that ideal 70°–80°F (21°–26°C) temperature.
- Do Not Disturb: Once you wrap your container and set it aside, resist the urge to move, shake, or stir it. Cultured buttermilk needs complete stillness to build its delicate protein network and firm up.
Frequently Asked Questions (FAQ)
Can I use whole milk instead of skim milk to make Cultured Buttermilk Khasa Chaach? Yes, absolutely! While this recipe uses skim or low-fat milk to keep the calorie count down, substituting whole milk will yield an even richer, thicker, and creamier homemade buttermilk. The preparation steps and setting times remain exactly the same.
Why did my homemade buttermilk not set properly and remain runny? A runny consistency usually points to one of two culprits: temperature or an inactive starter. If your milk was heated too high, it likely killed the lactic acid culture. Alternatively, if the fermentation environment dropped below 70°F (21°C), the cultures may not have had enough warmth to multiply. Finally, ensure your commercial buttermilk starter was fresh and contained live, active cultures.
How long does homemade Khasa Chaach last in the fridge? When stored in a tightly sealed glass jar or airtight container, your freshly made Cultured Buttermilk Khasa Chaach will stay fresh and delicious in the refrigerator for up to one week. The flavor may become slightly tangier as the days go by, which is completely normal for cultured dairy.
Can I use a portion of this recipe to start my next batch? Yes! Once you have successfully made this Cultured Buttermilk Khasa Chaach, you can save ⅔ cup (160 ml) of it to use as the starter culture for your next batch. This is a fantastic and economical way to keep a continuous supply of fresh buttermilk in your kitchen. Just make sure to use it within a week while the cultures are still vigorous!
