Those Hatco units look pretty nice, but they are expensive. There are some good deals to be had on them on ebay now and then though. I think there are pros and cons to both dry heat and moist heat, but if you are putting the slice back in the oven to heat it, I think the moist heat might be best. The oven should crisp it up again I would think. I think with dry heat it would probably be best to keep the pie in a box to keep it from drying out too much over time. I am just trying to think it through though as I am not yet open, so I have not dealt with this problem yet either. I hope you find the best solution for your problem. Good luck!
I’m wanting to keep this unit in another section of the resturant, so it would be a pain to run the slice all the way back to the pizza ovens to warm and crisp.
I want to crust to stay nice and crisp but not dry the toppings out…
unfortunately, I cannot think of a better way than crisping the pizza on a deck oven
I have a small deck oven, Castle Comstock, 19"x22" deck, up to 3 decks, cost little over $1000 and it cooks a good pizza, only about 6 per hour though
in summary, I do not know a holding box that will deliver the quality that the re-heat will,
good luck,
Sounds like you would be best of with a dry heat unit, and keep the pizza in a box to help it to not dry out. You could maybe use one of those little pizza/pretzel ovens to try and crisp it up. Not ideal but your situation sounds like it limits your options. Good luck!
