Can you use lemon to make yogurt starter?

Yogurt starter is a culture of live bacteria, specifically Lactobacillus and Streptococcus thermophilus, that are responsible for fermenting milk into yogurt.

Lemon juice is acidic and would kill the bacteria needed for yogurt production. It's used to make other things like lemon curd or to add flavor, but it wouldn't work in this instance.

To make yogurt, you need:

* Milk: Usually whole milk or a blend of whole and low-fat milk

* Yogurt starter: This can be purchased at the store, usually in small containers labeled "yogurt starter" or "yogurt culture."

* Warmth: The milk needs to be incubated at a warm temperature for several hours, allowing the bacteria to multiply and ferment the milk.

If you don't have yogurt starter, you can try a similar method using homemade sourdough starter, as it also contains beneficial bacteria. However, this is less reliable and may not produce the same results as a dedicated yogurt starter.
