If you can find fideo in your grocery store, it will save you a step. If you cannot, spaghetti will work. I need a gluten free noodle so I end up buying spaghetti myself.
Measure out 100g of your dry noodles and break them into small pieces. About 1/2" in length is the goal. I grab a small group of the noodles and break them into pieces with my hands until they are all broken into pieces.
In your best rice cooking pot with a tight fitting lid, add in 2 tbsp of butter over medium heat. Pour in the noodle pieces and stir to coat with butter.
Cook the noodles in the butter for 3-5 minutes until they begin to puff up slightly and begin to brown, this will help give them a toastier flavor. Stir often.
Once they have developed some color, add in the dry rice, onion powder, garlic powder, turmeric, and salt. Stir to coat with butter and toast the rice and spices for an additional minute or two. Keep them moving to prevent burning.
To cook this rice you will need 560g of liquid. If you want to use all broth, that's great. At my store most of them come in 2 cup (480g) packages. So I used 480g of broth and 80g of water to reach the total needed instead of buying 2 and having extra.
Add the liquid to the pot and bring to a rapid boil. This pot needs to come up to temperature in order to properly cook the rice. Once you reach a rapid, rolling boil, hold this for 60-90 seconds and then cover with a tight fitting lid and reduce the heat to low. Simmer for 18 minutes.
RICE NOTE: It is very important that you have a pot with a tight fitting lid and that you bring the liquid in the pot to a rolling boil before simmering. When I failed to do these two things during recipe testing the rice came out mushy on the exterior but still hard on the inside. The evaporation and steaming process is important in cooking the rice properly and these two things are must haves.
After 18 minutes, turn off the heat and allow the pot to sit covered for an additional 10 minutes to finish steaming.
After the 10 minutes are up, remove the lid and fluff up the rice. Taste test and adjust seasoning as needed. If you want it to taste like the boxed Rice-a-Roni, a sprinkling of MSG will do the trick.
