Can your grilled leg of lamb recipe be made in an electric roaster? And if so, what changes should I make to the recipe?

I have never used an electric roaster, but in the comments, the author says the marinade would be good with a bone in leg of lamb and to roast it however you normally do. Amanda and Merrill used a butterflied leg of lamb and broiled it.

I'm assuming you wouldn't butterfly it if using a roaster? The roasters I see online don't look very big.

I never heard back- the recipe is called Spiced "Leg of Lamb on the Grill
