You’re all wrong in fact. The microwave heats water particles. The exact reason you can cover a heating meal with a paper towel without it igniting. The glass of water is meant to alleviate the intensity of microwaves heating the pizza and crust, thus avoiding an overcooked, chewy crust.
Hydrocarbons (like the oils in cheese and crust) don’t absorb microwaves, but they are heated indirectly by water. To heat your pizza, you want to slowly heat the water. Slow heating keeps the crust dry while giving the cheese and meaty toppings a chance to heat.
Heating chemicals in a microwave is different from heating them on a hot plate! If you heat pizza sans water, the pizza absorbs all the microwaves. Water in the sauce and toppings quickly vaporizes and soggifies the crust. So, you can get a nice crust with unmelted cheese and cold toppings or a tough crust with hot toppings.

Why do you use a microwave oven?
The set frequency of a commercial microwave oven is designed to maximize heating of water-rich foods. In other words, a microwave oven is meant to heat water. Hydrocarbons (like the oils in cheese and crust) don’t absorb microwaves, but they are heated indirectly by water. To heat your pizza, you want to slowly heat the water.
Here’s what you do: Place a slice or two of pizza on a plate. Place a (microwave-safe) mug of tap water in the microwave right next to the plate. Corelle or Pyrex works best. Don’t use stoneware because it gets crazy hot. You can use a glass of water, but let it cool before retrieving it.
Ready to reheat that pizza? Here’s what you do: 1 Place a slice or two of pizza on a plate. 2 Place a (microwave-safe) mug of tap water in the microwave right next to the plate. Corelle or Pyrex works best. Don’t use stoneware because it gets crazy hot. You can use a glass of water, but let it cool before retrieving it. 3 Heat the pizza on high power about 45 seconds until it’s hot.
Most microwaves have rotating tables to increase the interaction between the beam of microwaves and your food. Chemists add a dummy load when heating samples to protect the appliance from reflected radiation (basically so the microwave isn’t running “empty,” which can cause damage). Usually, this is a glass flask of water or a beaker …
Microwaves pass through a waveguide into the “oven” part of the appliance, but at a preset frequency (typically 2.45 GHz).
So how does it work? The answer has to do with the interaction between microwaves and matter. First, heating a glass of water for 30-45 seconds in the microwave isn’t long enough to bring the water to a boil. So, you won’t fill the microwave with water vapor, which could ruin the crust.
Microwaves are electromagnetic waves that cause dipoles to rotate. The dielectric constant of a material reflects how efficiently microwaves produce heat. Water has a high dielectric constant; oil has a low constant.
What is the default cooking power for a microwave?
Most microwaves display 100% as the default cooking power. “That ensures things get heated more slowly and evenly,” Patel noted. Patel admits she had no desire to try the Domino’s Australia trick, which has been circulating on the internet for years.
Palak Patel, a chef at the Institute of Culinary Education, told TODAY Food that the hack works by diverting the moisture away from the pizza. But there are a few things to consider.
Just place the pizza on a baking sheet wrapped in foil, set the temperature to 275 degrees and heat for 25 minutes. Patel swears by the tip that she picked up while watching “America’s Test Kitchen” a few years ago. “This really works,” Patel said.
“If you have an older microwave without as much power, you’re probably going to need more than 30 seconds. It’s trial and error.”.
Domino’s shares hack for microwaving pizza with a cup of water. You might want to adjust the settings on your microwave. Whether you prefer your pizza thin and crispy or thick and doughy, we can all agree to pass on a soggy, microwaved slice.
