We conducted a controlled test comparing the heat retention of three food storage methods to evaluate their effectiveness in maintaining safe serving temperatures:
Glass baking dish (open, no cover)- Represents food left on the counter in a standard serving dish, an extremely common hosting scenario.
Glass baking dish with a tinfoil lid -Mimics a basic attempt at heat retention, often used to cover food before serving or transporting.
Host Modern thermal dish (primed with hot water, with secure lid)- Designed specifically to maximize heat retention and keep food at safe serving temperatures for extended periods.
Each was filled to 80% capacity with boiling water (initial temp ~192˚F) and monitored at regular intervals.
Results and Findings
Option 1 (No Lid - Open Dish):Rapid heat loss occurred almost immediately, dropping into the FDA danger zone (below 140˚F) within17 minutes. By30 minutes, the temperature fell to 123˚F, and at60 minutes, it had lost42%of its heat (102˚F).
Option 2 (Tinfoil Lid):The tinfoil cover significantly slowed heat loss. At30 minutes, the water remained at160˚F, and at65 minutes, it reached140˚F, lasting nearlyfour times longerthan the open dish before entering the danger zone. By90 minutes, the temperature was129˚F, reflecting a30% total heat loss.
Option 3 (Host Modern Thermal Dish):Priming the dish and securing the lidenhancedheat retention dramatically. At30 minutes, it held at182˚F(22˚ hotter than the tinfoil-covered dish). Even at2 hours (30 mins longer than option 2), it maintained147˚F,never entering the danger zone, with only a24% heat lossover time.
Conclusion
TheHost Modern Thermal Dish significantly outperformed both traditional methodsin maintaining food-safe temperatures. Compared to the tinfoil-covered glass dish, it:
Retained heat 4x betterover the first hour
Stayed above 140˚F for over two hours, ensuring food safety for extended serving periods
Prevented rapid temperature drops, keeping food at an optimal serving temperature
This test underscores the thermal efficiency of Host Modern’s design, making it an ideal solution for hosting, transporting, and keeping meals warm for extended periods without relying on external heat sources.
A "Real World" Example
I grabbed twoCostco stuffed bell pepper meals, cooked them in our glass baking dishes, and ran a simple test:
Option 1:Left one in the glass dish on the counter.
Option 2:Moved the other into ourprimed thermal dish.
Here’s what happened (other than me slightly over-cooking the peppers... don't judge)
Glass Dish (No Lid)– Peaked at 193˚F, but heat dropped fast:30 mins:162˚ //50 mins:140˚ (FDA danger zone) //90 mins:112˚ (58% heat loss)
Host Modern Thermal Dish– Peaked slightly higher at 197˚F and held heat significantly longer:30 mins:186˚ //60 mins:168˚ //90 mins:152˚ (Still well above the danger zone!)
Takeaway? The glass dish lost more than half its heat in 90 minutes. Our thermal dish kept food hot and safe nearly twice as long—perfect for serving and hosting without stressing about cold food.
