Let's explore the differences between a rice cooker that costs a few hundred thousand and one that costs a few million.
1. Choosing the Perfect Rice Cooker: Does a pricey pot make better rice than a budget-friendly one?
Let's delve into the distinctions between a rice cooker priced at a few hundred thousand and one in the million-dollar range.
Choosing Based on Capacity
When purchasing a rice cooker, the first thing to consider is its capacity. The capacity determines the number of people the rice cooker can cater to. Generally, a 2-liter pot is suitable for 1-2 people, a 3-liter pot for 2-3 people, a 4-liter pot for 3-6 people, and a 5-liter pot for 4-8 people. Choose the capacity based on the number of people in your household. Of course, it's good to opt for a larger capacity as a precaution for unexpected guests or if you plan to use the rice cooker for preparing other dishes. In essence, choosing a 4 or 5-liter capacity is sufficient for a typical family.
Choosing the Inner Coating
After selecting the capacity, the next step is the inner coating or the inner part of the pot. There are various types of inner coatings for rice cookers, including aluminum alloy, stainless steel, ceramic, cast iron, and multi-layer composite materials.
Most rice cookers on the market use an aluminum alloy inner coating, including the composite type. Aluminum conducts heat evenly and is easy to cast, and it can be combined with other metals or alloys, such as aluminum-steel alloy.
However, it's common knowledge that aluminum is toxic, and products made of aluminum used to hold salty, acidic, or hot food can easily precipitate harmful substances for the human body. Therefore, a non-stick coating is added to the inner coating of the rice cooker to isolate and prevent direct contact between the food and aluminum. The most common coating is Teflon (polytetrafluoroethylene), widely used in non-stick pans. However, if the coating is used for an extended period, it may corrode and reveal the aluminum underneath.
So now, many people are seeking non-coated coatings. Among them, a 304 stainless steel coating helps users not worry about the precipitation of harmful substances. Still, it has a downside of being prone to sticking, causing inconvenience during cleaning.
