Brace yourself for some guac gouging in advance of Superbowl XLVIII. After a cold spell in Mexico and Florida (damn you, polar vortex!), the cost of avocados is up almost 10 percent. Of course, restaurant guacanomics factor a whole host of extra costs into the final price, so even at an extra 20 cents per avocado, making the dip at home is still a relative deal. The better news: Largely recovered from the Great Wing Shortage of 2013, the cost of chicken wings this year is down 1 to 5 percent. [NYP, Related]
