Why does my homemade yogurt always turn out too runny and what can I do to fix it?

Don't worry, making homemade yogurt can be a bit tricky, but with some tweaks, you can achieve the perfect consistency. First, let's talk about the basics. You're on the right track by heating the milk, adding a yogurt starter, and incubating it. However, the key to thicker yogurt lies in the details.

The type of milk you use can indeed affect the consistency of your yogurt. Whole milk will generally produce a thicker yogurt than skim milk, as it contains more fat and solids. That being said, you can still achieve a thicker consistency with skim milk by adjusting other factors. One thing to try is heating the milk to a higher temperature (around 180°F to 185°F) before cooling it down to the incubation temperature (around 100°F to 110°F). This will help kill off any unwanted bacteria and create a better environment for the starter to grow.

Another important factor is the incubation time and temperature. Make sure you're incubating the mixture for the right amount of time (usually around 6 to 8 hours) and at the right temperature. If it's too cold, the starter won't grow properly, and if it's too hot, it can kill off the starter. You can try using a yogurt maker or a thermos to maintain a consistent temperature.

Now, let's talk about the starter. You can try adjusting the ratio of milk to starter, but it's not the only factor to consider. Using a high-quality starter with active cultures can make a big difference. You can also try adding a thickening agent like gelatin or pectin to help achieve a thicker consistency.
