There is a roast chicken recipe from Cooks Illustrated that I've made for years now. You spatchcock the bird (remove the spine and flatten it), place it on a broiler pan, fill the bottom of the pan with sliced potatoes, and roast at 500F for an hour or so. The chicken is good, and the potatoes both prevent the chicken drippings from burning and become delicious cooked in the chicken fat.
Recently when making the recipe I threw some sliced onions in with the potatoes and the flavor profile reminded me of a latke (Jewish potato pancake traditional around Hanukkah). This made me wonder whether I could shred the potatoes rather than slice them and make a giant chicken-fat-fried latke to go with my chicken.
My question is whether I should add a binder to the shredded potato (and if so, if I ought to use more or less than a standard latke recipe). Normally to make latkes I add flour and egg to the shredded potatoes and grated onion. My concern is that the extended high temperature cooking might be too much for the binders, causing them to overcook.
