Homemade yogurt offers probiotic benefits and endless flavor possibilities. **Detailed Process**:

**1. Sterilization**: Boil the slow cooker insert and utensils to eliminate competing bacteria.

**2. Milk Preparation**:

- Use 1 gallon of whole milk for creamier yogurt. Heat on **LOW for 2.5 hours** until it reaches 180°F (82°C), denaturing proteins for thicker results.

- Cool milk to 110°F (43°C) using an ice bath around the insert.

**3. Inoculation**: Stir in ½ cup store-bought yogurt with live cultures (e.g., _Lactobacillus bulgaricus_ and _Streptococcus thermophilus_).

**4. Incubation**: Wrap the slow cooker in towels to maintain heat. Let ferment for **8-12 hours**—longer incubation increases tanginess.

**5. Straining (Greek Yogurt)**: Line a colander with cheesecloth, drain yogurt for 2-4 hours, and reserve whey for smoothies or baking.

**Flavor Variations**:

- **Vanilla Bean**: Add 1 scraped vanilla pod post-incubation.

- **Berry Swirl**: Layer with homemade chia jam.

**Science Behind It**: Bacteria consume lactose, producing lactic acid that thickens milk. Temperature control is critical: <110°F slows fermentation; >120°F kills cultures.

**Troubleshooting**:

- **Grainy Texture**: Overheating milk. Use a thermometer.

- **Too Thin**: Extend incubation time or add ¼ cup powdered milk before heating.
