I do not know about this specific rice. Generally, rice has a high GI. However, what you eat with it can change the GI of the whole meal.
For example, if you eat it with a curry, the fat in the sauce can slow down the absorption.
Working from the GI can be a useful start but your body is the best measure. If you are using a Libre, you can try it and see when your BG starts to rise. If it rises too high but comes down to normal, you have taken your bolus too late. If your levels go too low, you have taken it too early.
