This one is not my own recipe nor variation, but from here:
Tips: You can get everything at Trader Joes (currently), and if you use their Dijon mustard, that happens to be very sharp, I think it’s a bit better for this recipe than, say, Grey Poupon Country Dijon, a staple I always have in my kitchen.
I use this one, that cost only about $15: http://www.amazon.com/Rival-RC61-6-Cup-Rice-Cooker/dp/B000ETXV94/
One downside of this super-cheap, small model is that the plastic handles on the lid and steamer tray aren’t dishwasher-safe. Also, if you fill it to prepare its maximum capacity, the water will occassionally spit out the vent hole when it’s boiling, until some of it is absorbed. This can be avoided by always placing the included steamer tray on top, even when you have nothing to steam. :)
