Rice has no impact on me at all really, it seems to digest slowly and steadily for me. I tended to go hypo quite quickly when bolusing for it, so I tried split bolus and still went hypo. So I either inject after I've eaten it if I'm having other carbs in the meal, or as most often happens I reduce bolus for it, my standard bolus is 1:20 at dinner time and 1:15 at lunch but for the rice portion I do 1:25 and 1:20 instead and inject mid meal, that does it. I'm not really a fan of rice, but I do like the occasional risotto and I used to love apple muller rice, it was the apple muller rice that brought about the realisation that I needed less bolus, they're pretty carb heavy and I'd bought a six pack (I have food obsessions, always have done, I'll eat a muller rice every day for a week then not touch one for 12 months....weird I know 🙄) and had a hypo at 3pm every day, had to be the rice but didn't do much experimenting because I didn't really believe it what with all that sugar in there, then I had a risotto phase about six months later and sure enough the same thing happened. I can practically go bolus free with a couple of pieces of veggie sushi which was a shocker. Typical, my body loves a bit of rice, but my tastebuds don't really agree, though come to think of it I haven't had a muller rice for about 12 months so maybe it's time!
