Some newspaper featured this in their food section sometime ago but I never could find the recipe again. I created it from memory and what I would want it to taste like and it turned out incredible. I served it at Rosh Hashanah and it was devoured in a way I've never seen (seriously - it's a casserole - but it was mobbed like it was the last edible on earth). It’s so good, people will forget whatever the main dish you’re serving. I serve this for Passover, or Rosh Hashanah, or Thanksgiving and it would be wonderful at Christmas or Easter too. Or daily. It has a secret ingredient that you might protest at but it is kosher and the transformational element in this memorable side dish. Oh, why Madras? It's the brand of curry powder I use. The shredded apples (btw) tend to 'melt' or cook into the hot potatoes as you are mashing it all up.
