Instructions

1. Measure the amount of milk needed for your milkshake and place it in a saucepan. Add the eggs, making sure to wash your hands if any of the egg whites leak out onto your hands.

2. Whisk the egg into the milk in quick, light strokes until the egg is fully incorporated and the yolk is no longer visible. If you don’t have a whisk, a fork will do the job.

3. Heat the milk mixture on medium to low heat, whisking to prevent any clumping. Watch the edges of the milk for small bubbles that indicate the milk is getting hot. You want the milk to reach a temperature of at least 160 degrees Fahrenheit without boiling over. A spoon dipped into the milk should come up coated, or use a thermometer to check the temperature.

4. Remove the pan from the heat as soon as the milk reaches the correct temperature. Pour the milk mixture into a blender over your frozen fruit or chocolate chips. The hot milk will melt the chocolate and soften the fruit.

5. Blend on low until the ingredients are smooth, then proceed to add your other milkshake ingredients, such as ice cream and flavor extracts. If the chocolate or bits of frozen fruit stick to the sides of the blender, stop the blender and use the spatula to push the ingredients down.

6. Pour the milkshake into glasses that have been chilled, and serve immediately.
