I have a rice cooker at home. I eat rice often.
I have rice with natto, nori, or kimchi. Today I had furikake sprinkled on top of my rice. It's furikake I bought at a British supermarket. It's good.
Recently, the novel “Butter” became a huge hit. This book features a story about eating rice topped with butter. I imagine quite a few people like butter on rice. I haven't tried it myself yet.
