Fresh garlic (minced) has a stronger flavour than dried forms. It depends on what your goal is. Wouldn’t powdered garlic be more convenient for a rub? My ex and I used to poke holes in a roast with the tip of a knife and insert slices of garlic before roasting. The result was really yummy. Unfortunately, garlic is not very popular with most of the people I’m now cooking for.
When I make sauce, I often take the advice of an Italian friend of mine and add the garlic late in the process. She maintains that over-cooking garlic robs it of flavour.
My mother used to have a recipe that called for—I kid you not—40 bulbs of garlic. It was delicious.
And for those who can get there, the town of Saugerties, New York, has an annual garlic festival in the summer. No vampires within hundreds of miles!
