In Istanbul, the kumpir potatoes are giant (huge!), the fillings are excessive and you wonder how you will ever get to the end (by yourself) of this very good sort of mashed potato sandwich.
Ingredients
1 very large roasting potato such as russet (idaho), king edward, bintje (yellow finn) or similar
Preheat the oven to 200°C (400°F). Scrub the potato with a brush, pat dry with paper towel and prick with a fork in about six places all over. Bake in the oven for about 45 min
