Is it possible to make bacon at home?
Sure. Michael Ruhlman has a post about it, and I think there was an episode of Good Eats that described the process pretty well, too. I'm not sure what you can get at the butcher in India, but you'll want to find the belly of the pig.

What you do is rub the meat with a cure, which is a mix of salt, sugar, seasoning, and "pink salt" (a curing salt that is part regular salt and part sodium nitrite). Leave it in your fridge in a ziploc bag for a week or covered on a tray, flipping it over daily so that it cures evenly, then rinse it off. At that point you can roast it in a low oven, smoke it, or hang it to dry.
