If you asked my frank opinion, I will tell you that Bagadels are hard work. You are better off buying those frozen ones from the supermart or those piping hot ones from your fav malay store. If you are still not convinced, try making them yourself.
2 medium size potatoes
1 egg (beaten)
Salt and pepper to taste
Peel and cut potatoes into wedges. Heat up your pan with oil (not too hot). Fry the potatoes, preferably 3 – 4 pieces at a time. Scoop them out when they turn slightly golden brown. Mash them while they are hot (caution: hot!)
Mix the finely chopped shallots and garlic into the mashed potatoes. Roll the mixture into balls (slightly flatten and not too big). Make sure they are firm (if you really wana make sure they hold tog, add some bread crumbs). Egg wash them (aka coat the potato ball evenly with a thin layer of beaten egg). Fry them till they turn a nice brown like this:
I know i know it looked abit oily (i could have done better with my photography) but hey all yummy food are not very healthy (I am just showing you the reality). Anyway, for a less PITA version, you can boil the potatoes and mash them instead of frying.
P.S. Good luck!
