Ingredients You’ll Need

* **Milk:** The most important ingredient! You can use whole milk, 2% milk, or even non-dairy alternatives like soy milk, almond milk, or coconut milk. Whole milk will produce the thickest and creamiest yogurt. Keep in mind that using ultra-pasteurized milk can sometimes hinder the yogurt-making process; regular pasteurized milk is usually preferred. Organic milk is also a great choice.
* **Yogurt Starter:** This contains the live and active cultures that will ferment the milk into yogurt. You can use store-bought plain yogurt with live and active cultures (make sure it’s not flavored or sweetened) or purchase a yogurt starter culture online. A good starter will have a variety of bacteria strains.
* **Optional Sweetener:** If you prefer sweetened yogurt, you can add a sweetener of your choice. Honey, maple syrup, sugar, or even stevia can be used. Add the sweetener after the yogurt has finished fermenting and chilling.

Equipment You’ll Need

* **Slow Cooker:** A 6-quart slow cooker is ideal, but smaller or larger sizes can also work. The key is to have a slow cooker that maintains a consistent temperature.
* **Thermometer:** An instant-read thermometer is essential for monitoring the temperature of the milk during the heating and cooling phases.
* **Whisk:** For mixing the milk and yogurt starter.
* **Measuring Cups and Spoons:** For accurate measurements.
* **Clean Jars or Containers:** For storing the finished yogurt. Glass jars are ideal.
* **Cheesecloth or Fine-Mesh Strainer (Optional):** For straining the yogurt to make Greek-style yogurt.
* **Towel or Blanket:** For insulating the slow cooker during the fermentation process.

## Step-by-Step Instructions: Making Slow Cooker Yogurt

Here’s a detailed guide to making delicious, homemade yogurt in your slow cooker:

**Step 1: Scald the Milk**

* Pour the milk into your slow cooker.
* Turn the slow cooker to the “high” setting.
* Using your thermometer, monitor the temperature of the milk. You want to heat the milk to 180-185°F (82-85°C). This process, called scalding, denatures the milk proteins, resulting in a thicker yogurt. This can take anywhere from 1 to 3 hours, depending on your slow cooker. Keep an eye on it to prevent it from boiling over.
* Stir the milk occasionally to prevent scorching on the bottom.

**Step 2: Cool the Milk**

* Once the milk reaches 180-185°F (82-85°C), turn off the slow cooker.
* Remove the ceramic insert from the slow cooker and allow the milk to cool to 110-115°F (43-46°C). This is crucial because temperatures above this range can kill the beneficial bacteria in your yogurt starter. This cooling process can take 1-2 hours. To speed things up, you can place the insert in an ice bath, being careful not to get any water into the milk.

**Step 3: Add the Yogurt Starter**

* In a small bowl, whisk together a couple of tablespoons of the cooled milk with the yogurt starter. This will help to temper the starter and prevent it from clumping.
* Pour the mixture back into the slow cooker with the rest of the cooled milk.
* Gently whisk to combine thoroughly.

**Step 4: Incubate the Yogurt**

* Return the ceramic insert to the slow cooker.
* Wrap the slow cooker in a thick towel or blanket to insulate it and maintain a consistent temperature. This is important for the fermentation process.
* Incubate the yogurt for 8-12 hours. The longer you incubate it, the tangier the yogurt will become. Start checking the yogurt after 8 hours to see if it has reached your desired consistency and tanginess. For a milder yogurt, 8 hours is usually sufficient. For a tangier yogurt, let it incubate for up to 12 hours. Do not disturb the slow cooker during incubation.

**Step 5: Check for Set and Chill**

* After the incubation period, carefully check the yogurt. It should have a slightly thickened consistency and a tangy aroma. If it still seems too thin, you can incubate it for another hour or two.
* Once the yogurt has set, remove the ceramic insert from the slow cooker and refrigerate it for at least 4 hours, or preferably overnight. This will help to further thicken the yogurt and stop the fermentation process.

**Step 6: Strain (Optional) for Greek-Style Yogurt**

* If you prefer Greek-style yogurt, which is thicker and creamier, line a colander with cheesecloth or a fine-mesh strainer.
* Pour the yogurt into the lined colander.
* Place the colander over a bowl to collect the whey (the liquid that drains from the yogurt).
* Refrigerate the yogurt for 2-4 hours, or until it reaches your desired consistency. The longer you strain it, the thicker it will become.
* Discard the whey or save it for other uses, such as adding it to smoothies or using it in baking.

**Step 7: Sweeten and Flavor (Optional)**

* After chilling and straining (if desired), you can sweeten and flavor your yogurt to your liking.
* Stir in your favorite sweetener, such as honey, maple syrup, or sugar.
* Add flavorings such as vanilla extract, fruit preserves, or chopped fresh fruit.

**Step 8: Store and Enjoy**

* Store the finished yogurt in airtight containers in the refrigerator for up to 1-2 weeks.
* Enjoy your homemade slow cooker yogurt plain, with fruit, granola, or in your favorite recipes.

## Tips for Success

* **Use a reliable thermometer:** Accurate temperature readings are crucial for successful yogurt making.
* **Avoid disturbing the slow cooker during incubation:** This can disrupt the fermentation process.
* **Don’t over-incubate:** Over-incubating can result in a very tangy and sour yogurt.
* **Sanitize your equipment:** Cleanliness is important to prevent unwanted bacteria from contaminating your yogurt.
* **Experiment with different types of milk:** Explore different types of milk to find your favorite flavor and texture.
* **Adjust incubation time for desired tanginess:** Incubate longer for tangier yogurt, shorter for milder yogurt.
* **Save some yogurt for your next starter:** You can use a few tablespoons of your homemade yogurt as a starter for your next batch.
* **If using a yogurt maker function:** Some slow cookers have a yogurt making function. This automates the temperature control and simplifies the process further. Follow your slow cooker’s instructions for the yogurt function.

## Troubleshooting Common Issues

* **Yogurt is too thin:** This could be due to several factors, including:
* Insufficient scalding of the milk.
* Using ultra-pasteurized milk.
* The starter culture was old or not active enough.
* The incubation temperature was too low.
* Insufficient incubation time.
* **Yogurt is too sour:** This is usually due to over-incubation. Reduce the incubation time in your next batch.
* **Yogurt has a grainy texture:** This can be caused by overheating the milk during the scalding process. Use a thermometer to carefully monitor the temperature.
* **Yogurt didn’t set:** This could be due to:
* The starter culture was not active.
* The incubation temperature was too high or too low.
* The slow cooker temperature fluctuates too much.

## Flavor Variations and Add-ins

The possibilities for flavoring your homemade yogurt are endless! Here are a few ideas to get you started:

* **Vanilla Yogurt:** Add 1-2 teaspoons of vanilla extract after chilling.
* **Fruit Yogurt:** Stir in your favorite fruit preserves or chopped fresh fruit.
* **Honey Yogurt:** Drizzle with honey after chilling.
* **Maple Syrup Yogurt:** Stir in maple syrup after chilling.
* **Lemon Yogurt:** Add lemon zest and a squeeze of lemon juice after chilling.
* **Chocolate Yogurt:** Stir in cocoa powder and a sweetener of your choice after chilling.
* **Coffee Yogurt:** Add instant coffee granules or brewed coffee extract after chilling.
* **Savory Yogurt:** Add herbs, spices, or even chopped vegetables for a savory yogurt dip or spread.

## Using Non-Dairy Milk

While cow’s milk is the most common choice for making yogurt, you can also use non-dairy milk alternatives like soy milk, almond milk, and coconut milk. Keep in mind that the texture and flavor of the yogurt will vary depending on the type of milk you use.

* **Soy Milk Yogurt:** Soy milk produces a relatively thick and creamy yogurt, similar to cow’s milk yogurt. Choose unsweetened soy milk for best results.
* **Almond Milk Yogurt:** Almond milk yogurt tends to be thinner than cow’s milk yogurt. You may need to add a thickening agent like tapioca starch or arrowroot powder to achieve a desired consistency.
* **Coconut Milk Yogurt:** Coconut milk yogurt is rich and creamy, with a distinct coconut flavor. Use full-fat coconut milk for best results. Some brands are easier to work with than others.

When using non-dairy milk, it’s often helpful to add a stabilizer like agar-agar or pectin to help with thickening. Follow the package instructions for the specific stabilizer you are using.

## Safety Considerations

* **Temperature control is crucial:** Ensure the milk reaches the correct temperature during scalding and cools to the appropriate temperature before adding the starter to avoid killing the cultures.
* **Cleanliness is paramount:** Always use clean equipment and containers to prevent contamination.
* **Refrigeration is key:** Refrigerate the yogurt promptly after incubation to slow down the fermentation process and prevent spoilage.
