Time & Temperature (NYC)Câu 71 / 240
A cook needs to cool a large pot of stock quickly to meet NYC limits. The most effective single step is to:
a.Cover it tightly and leave it deep in the pot in the walk-in
b.Set it on the counter with a lid
c.Transfer it to shallow pans and place them in an ice-water bath, stirring, then refrigerate loosely covered
d.Add hot water to thin it out
Giải thích
Transferring stock to shallow pans in an ice-water bath and stirring dramatically increases surface area and heat transfer, helping meet the 140°F-to-70°F-in-2-hours target. A deep covered pot or counter cooling traps heat and fails the limits. Adding hot water only slows cooling.
