A lot of dishes include a small amount of meat or fish or something else with a strong flavor, and then a large portion of rice or mashed potatoes or spaghetti, or something else that is comparatively flavorless. What's the word for that latter part?
"The rice on my plate is the _____ for my meat"
"Here are some meat balls, with rice as their ______"
I'm not sure if English has a word for this. In Russian, there's the word "гарнир" ("garnir"), but the English word that sounds like it, "garnish", seems like a false cognate, because it means specifically a decorative extra part of a dish.
