i am in the uk so don't know your brand of rice pasta, but generally rice or corn pastas need to be boiled very quickly (high heat) in plenty of water in order to give a texture similar to wheat.
it is best to put it in a creamy sauce (doesn't have to be dairy, a tomato based sauce with a little corn flour thickener would give a creamy consistency) in order to hide the slightly strange texture.
wheat free pasta does not work well when tossed with a little oil and fresh herbs, italian style. the oil just makes the pasta soggy around the edges and the herbs don't stick to the pasta.
you're better off cooking the rice as rice (instead of pretending it's pasta!) and adding some lovely stir fried vegetables (plus meat or egg as needed). remember brown rice needs more water and much more cooking than white rice.
you should not cook it in a japanese / chinese rice cooker, unless you have a preference for chewing little pieces of cardboard. rice cookers only work for white rice.
the best way to cook brown rice is to do the (vegan/sugar free/gluten free) west african recipe 'jollof rice', which is really really yummy.
i discovered it by working with some africans who were simply unable to talk to me one day because of a heated debate about jollof rice (was the ghanian style better or the nigerian one?). i gave up trying to get their attention and asked them for a recipe.
when i tried making it at home, i realised why they were ignoring me, as it was so delicious!
i brought some to work one day, and soon became an honorary african
actually, i can't find a vegan version on line, but i remember i did it vegan. i now have my own recipe in my head that does not use any weights or measures, so there is no point in me writing it down.
maybe it was a fasting season when i made it, but you can follow this recipe: http://allrecipes.com/Recipe/Jollof-Rice/
and simply miss out the chicken and add more spices or a stock cube. you could also do it with other meats or fish (add fish just after the veg so you don't cook it too much).
to make it a balanced meal, simply add some stir fried or boiled/steamed/whatever mixed vegetables on the side.
i hope you will excuse the detour on this thread about jollof rice (especially when you discover how delicious it is!)
