Rice shortages, hoarding, cost of transporting to the market (due to the skyrocketing oil prices), and now increasing wheat prices are constantly in the news and make for sobering thoughts. People speak of how difficult it is in the provinces, lining up for rice that is barely edible, stretching out their budgets to feed the children on gruel.

It can be boiled, broiled, baked, fried, sauteed, mashed, hashed, matted, stewed, and even makes for tasty bread. Get yourself a spud today.
