What is the Kotori inner bowl made from?
During our many years of selling and supporting Zojirushi rice cookers, we noticed that rice cookers available across the UK, Europe and USA predominantly used inner bowls with Teflon or similar non-stick coatings.
We received many questions and comments from customers about inner-bowl materials, and we decided that we wanted to offer a different type of cooking surface.
Our solution was the Ninja Bowl – an inner bowl featuring a premium, durable 2mm-thick ceramic coating designed specifically for Yum Asia rice cookers.
Why We Created the Ninja Bowl
We wanted to provide customers with an alternative to conventional non-stick coated inner bowls, while still delivering the excellent cooking performance and durability expected from a premium rice cooker.
The Ninja Bowl combines:
2mm-thick ceramic coating
Durable, hard-wearing construction
A specialised honeycomb structure for heat distribution
Clear, easy-to-read measurement markings
A cooking surface designed for excellent non-stick performance
The result is an inner bowl designed for regular everyday rice cooking while maintaining excellent heat distribution and durability.
BPA, PTFE and PFAS Free
The Ninja Bowl is designed without BPA, PTFE or PFAS, including PFOA and PFOS.
This was an important consideration when developing the bowl because we wanted to provide customers with a ceramic-coated alternative to the conventional non-stick surfaces commonly found in rice cookers.
The ceramic cooking surface is designed to provide excellent release properties without relying on a PTFE-based coating.
Honeycomb Heat Distribution
The Ninja Bowl incorporates a special honeycomb structure within its design.
This helps heat to disperse more evenly across the surface of the inner bowl, creating a more consistent cooking environment.
Even heat distribution is particularly important when cooking rice, helping the cooker to provide more uniform cooking throughout the bowl rather than concentrating heat in one particular area.
Clear and Durable Measurement Lines
Getting the correct water-to-rice ratio is fundamental to producing consistently good rice, so we also paid close attention to the measurement markings.
Rather than simply stamping the level markings into the bowl, the Ninja Bowl uses silk-printed measurement lines.
These are designed to be:
Clear and easy to read
Hard wearing
Easy to identify in lower-light conditions
Convenient for accurately measuring water
This means you can quickly identify the appropriate water level for the amount and type of rice you're preparing.
A Premium Alternative
The Ninja Bowl is one of the features that makes Yum Asia rice cookers different.
We listened to what customers were asking for and developed an inner bowl that combines a durable ceramic coating, thoughtful heat-distribution design and easy-to-read measurement markings.
2mm ceramic coating + honeycomb heat distribution + BPA, PTFE and PFAS-free construction = the Ninja Bowl.
It was designed to give customers a premium, durable and practical cooking surface for everyday rice cooking.
