How Can I Tell If Yogurt Has Curdled?

It is easy to determine if yogurt has curdled.

Curdled yogurt is unpleasant both in taste and texture. Fortunately, it is relatively easy to identify. You simply need to observe, touch and smell the yogurt to ascertain if it is curdled. Chances are, if your yogurt has been stored at warm temperatures for an extended period of time it may be curdled. If you think this is the case, throw the yogurt out without eating it. In addition to an unpleasant taste, it might make you sick.

Instructions

1. Open the container and note the smell. A sour or sulfury smell is a sign that the yogurt is curdled.

2. Observe the yogurt. If the yogurt is thick and lumpy, like cottage cheese, it is curdled. Stick a utensil in to determine the thickness. Curdled yogurt will provide more resistance than its standard consistency.

3. Scoop a small sampling from the container with a spoon. Take a minute portion on your tongue. Curdled yogurt will taste bitter and very unpleasant. If the yogurt tastes like that, it is most likely curdled and should be thrown away immediately.
