Serious burns can occur when working with melted sugar. One recipe said to have ice water at hand for accidents. I would expect a warning at the very top of the recipe not at the very end where I did find some warnings. Yes, we all should read the recipe before beginning but you know how that can be.
For inexperienced cooks who are trying these types of very simple recipes I would hope they were warned of the danger of melted, hot sugar.
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
