Making stovetop potroasts
My mother taught me to insert bits of garlic into slits made into the flesh of the roast before searing and then cooking it, something like what's described here.

Some people like cloves in there as well, though I more prefer that with bbq pork. For lamb, it's garlic and green olives. So, accordingly, you should be able to get creative and experiment with injecting some other things so the roast will take on flavors you prefer.
