Sharp Thinking

cooking with superheated steam is all the rage, and Sharp sells more superheated steam ovens than anyone



Take a step back and think about the food we all consume. The majority of what we cook and eat is comprised mainly of water and most thrive and grow in bountiful rainfalls. Think about the vineyards that absorb the moisture of a late summer evening when fog fed by ocean breezes rolls in and shrouds the hills of Napa and Sonoma counties. Or the juiciness of a ripe peach. Or how plant life and animals depend on water for survival. Not to mention that when we cook, we often use water. Poaching, simmering, boiling, blanching, braising, stewing, pot roasting, steaming and en papillote. Water plays such a fundamentally important role in our lives, especially in our kitchens, that we sometimes take it for granted.

We also take for granted what is happening to those water-based foods we put in our ovens. Traditional ovens can dry out the food, leaching out the nutrients and significantly diminishing the taste. It’s no wonder professional chefs like to rub some butter on steaks once they come out of the oven to make your first bite savory and delicious.

There is an evolution happening in our kitchens today that is dynamically changing how we think about cooking food and how to provide our families with the healthiest meals possible. And it has to do with water. From foodies to home cooks to elite name-brand chefs, we are witnessing a revolution and a revelation with the latest technology being deployed in homes and restaurants around the world. Cooking with superheated steam.

cooking with steam

Steam cooking is one of the most ancient methods used for preparing food. Archaeologists have found the chards of ceramic pots at different digs around Japan that reveal the cooking habits of the people in the Jomon period. These pots date back as far as 15,000 years to the last ice age. Some used for cooking are the earliest incarnations of what we now call the nabemono, or hot pot.

Every family made its own pots for basic needs like cooking and storage, and later with spare time, pottery with stands and other ritual vessels were produced. The Yayoi people made different types of pots for different uses. Jars for cooking, pedestaled bowls used like dishes for serving foods, and vases for storing food and water. Perforated jars were used for steaming foods such as rice and oysters.

the Yan steamer

In China during the Qing Dynasty, in the small town of Jianshui a potter by the name of Yang Li created a steam-pot with a hollow tube in the center. This was used primarily for steamed chicken. Versions were created that resemble today’s double-boilers. This type of steam pottery is known today as a Yan bronze steamer. It consists of a zeng, or deep upper bowl with a pierced bottom, which was placed upon or attached to a lower, legged vessel known as a li.

Water contained within the li would be boiled, steaming the food in the upper bowl. Yan first appeared during the late Shang dynasty (c. 1300–1046 BCE), around the 12th to 11th century BCE, and was a popular form of steamer throughout the Western Zhou (c. 1046–771 BCE) and early Spring and Autumn (770–476 BCE) periods.

The yan pictured here is from the early Western Zhou period. The decoration on the upper section is fairly restrained, with only a narrow ornamental band of animal masks below the lip.

Fast forward to the 21st century and steam pots (double boilers) are a staple in any serious kitchen. Steamer ovens come in many shapes and sizes and can be found in restaurants and bakeries where the steam cooks food faster and helps produce crispier crusts on bread.

Superheated steam is steam put in contact with additional heat, which makes the temperature of the steam raise with pressure. Water vapor heated to 485° F keeps the heat evenly distributed inside the oven to eliminate hots spots and provides a more efficient way to transfer heat to the food. The food browns, but the inside stays moist and nutrients, vitamins and antioxidants aren’t lost in the cooking process.

In a recent study published in the Korean Journal for Food Science of Animal Resources, superheated steam food samples scored the highest among the sensory characteristics, tenderness, juiciness and overall acceptability. After extensive research, steamed vegetables maintained a better texture quality than boiled vegetables and steamed sweet potatoes had an increase in antioxidant activity.
