I opt for the bigger capacity with the option of single or double tier. It's always a good idea to have the flexibility of expansion :)
So here you can see that it basically comes with 2 bowls. 1 slightly bigger suitable to cook soups, porridge, stews etc and a smaller bowl that u can use to steam smaller items or even rice for a single portion.
The concept behind the electric lunch box is basically steaming. All you need to do is pour water (I usually use hot water) at the lowest compartment of the lunch box and it will create steam to cook the raw food ingredients. Yes, your ingredients can be raw and the steam will cook it till it's fully cooked! In general, I noticed that 20 - 30 mins is all it takes to fully cook the ingredients. For soups (especially if I want it to be more flavourful, I will cook up to an hour. As long as there is water in the lower compartment, it will continue to steam and cook. So during the times when I am cooking a dish for longer period of time, I either add more water at the beginning of the process or add water after a while to keep the electric lunch box cooking.
Here are some of the dishes I have tried in office. They are all simple, one dish items.
Quinoa with salmon, carrots and edamame beans
Quinoa with steamed salmon, golden mushrooms and tomato
Corn, carrot and pork ribs soup with rice
Claypot chicken rice! Yums!
Pork porridge with cabbage, carrot and century egg
You can see from the dishes I tried above that it's simple to use this electric lunch box. Just need to exercise some creativity on what you want to cook for the day.
I ordered my electric lunch box from Qoo10 previously at around $20+ and it is a product made in China. You can use a travel adaptor for this lunch box as the original plug will be China plug. I have been using the cooking regularly for close to a year and is still working well.
For readers out there who find cooking to be a chore, this is something that you can consider to start simple healthy cooking. :)
