Can you slow cook a meal without a slow cooker?!

Can you slow cook a meal without a slow cooker?

I want to cook silverside slow cooked, but don't have a slow cooker. Is it still possible?
Also any silverside recipes would be great!

Thanks

You can make a slow cooker using to pots and make a double boiler. You would need 2 pots, where onefits inside of another, but also makes a leas around edges. Place just enough water in bottom pot to just barely float the top pot, and top pot must have a lid for it. Turn stove on simmer, and heated water with slow cook your food, without burning it. Hope this helps
