Garlic

Garlic, called "bawang" or "ajos" in the Philippines, is known for both its culinary and medicinal purposes. It has a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking. It is a fundamental component not just in Philippine and Asian cuisines but also in the other parts of the world. We often pair it with onion and tomatoes, a good pair for sautee.
Garlic is claimed to help prevent heart disease including atherosclerosis, high cholesterol, high blood pressure, and cancer. Garlic is also alleged to help regulate blood sugar levels. Oh, I remember my grandmother eating a whole bunch of this pungent spice, that is why.

With mortar and pestle, one can crush it into pieces. But what I usually do is first separate it into cloves, cut the harder tip and peel the skin. I then slice it into preferred size. Easy.
