buy a bottle of cheap whiskey, a bottle of garlic infused olive oil, some fresh cilantro, a sauce thickening agent (corn starch or instant mashed potatoes powder) and one small eggplant.
cut eggplant in slices, put it on an aluminum foil mold, drown it with the olive oil (save some olive oil for later) and some salt, put it to cook on the oven until its brown and tender. the eggplant absorbs the olive oil.
Take the cooked eggplant slices out, cut the peel off and save them. put the 'insides' on a bowl.
Chop the cilantro up finely and toss it into the bowl and mix it all. Pour some more olive oil in there. Then add a half cup of whiskey.
Transfer it all to a large saucepan (minus the peels) and bring it to a simmer while mixing slightly. You want the whiskey to slightly evaporate. Add the thickening agent and like with any sauce, let it heat until its ready.
Its rather tasty and not overwhelming in flavor as long as you dont pour it on the meat... a dab/dash will do. Its rather good though.
I use it on honey cured ham (store bought I admit

) and it gives it an interesting additional flavor without ruining the flavor of the ham itself.
I've got weird tastes so not sure if this will be for you.
