*RAW EGG WARNING
* Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, eggs with intact shells, and avoid contact between the yolks or whites and the shell.
