Grandma's Yorkshire Fish Cakes with Mushy Peas is a classic British dish that is both comforting and delicious. The fish cakes are made with flaky white fish, mashed potatoes, and a blend of herbs and spices. They are then coated in breadcrumbs and fried until golden and crispy. The mushy peas are made by simmering peas until soft and then mashing them with butter and a touch of mint. Serve these fish cakes with a side of mushy peas for a hearty and satisfying meal.
