I am in the privileged position of knowing that, despite what some may tell you, there is in fact such a thing as "too much garlic".
One of the first dishes I made for a family potluck as an adult was a broccoli salad thing. I followed a recipe. But I thought "clove" meant "head". 6 servings of salad with an entire, *large* head of garlic, minced. It was literally painful to eat due to the astringency.
