There are two methods to check if a curd is cooked: - Use a kitchen thermometer to check the temperature of the curd. It is ready when it reaches around 82 degrees Celsius (180 degrees Fahrenheit). - Dip the back of a spoon or spatula in the curd, draw a line with a finger (be careful, it will be hot) and tip it down. If the curd looks liquid and runs over the clear line, it's not ready. If the curd looks thick and the line stays clear, it's ready.
