what is dubar basmati rice - #24895

I am feeling a bit confused and need some insights. Lately, I’ve been hearing about this thing called "dubar basmati rice." I was at a family gathering, and my aunt was talking about it. She said something like, “Dubar basmati rice is the best for making biryani,” and other folks around nodded in agreement. I honestly didn’t even know there were different types of basmati rice! I mean, I always just grabbed what was on sale at the store. So, what is dubar basmati rice? Is it different from regular basmati rice? I've noticed that when I cook basmati, it turns out all sticky and clumpy sometimes, and I’m wondering if using dubar basmati rice would make a difference. Like, I’ve read that it can affect the aroma and flavor, but I’m unsure. Is it worth trying or am I just overthinking a simple rice choice? Any context would really help me get my head around this!
