I have not tried the garlic one. I like to roast at least a half dozen heads, squeeze the garlic into a small container and put it in the fridge. I usually have it used up in a week or 2.
Love roasted garlic! I made my usual whole beef tenderloin for the family Christmas dinner and also whipped up a roasted garlic, Greek yogurt, sour cream, horseradish sauce to go with. It was a hit.
