We are big curry fans. However, we are also #lowcarb , so we avoid rice.
The typical #keto solution is cauliflower rice. Not to our taste.
A much better solution is finely shredded Savoy cabbage. Fulfills the requirement of mopping up sauce & is neutral enough to go with any curry. Also cheap & easy to make.
Core the cabbage, cut into quarters. Slice finely. Place in heavy pan over high heat. Small amount of water & salt. Stir constantly until cooked. Toss in butter.
