Early Spring means Ramp Season in the midwest.  
Ramps (Allium Tricoccum), a cross between onions and garlic, have a very short season - a few weeks - so you have to enjoy them while you can.   They are the first green edible item to emerge after winter -- kicking off the new growing season.  For seasonal eaters that means the days of root vegetables, root vegetables, and more root vegetables are over.  There is a great local organization called 
The Land Connection, and its big fundraiser, recently held, is called RampFest.  Local chefs cook up dishes highlighting ramps.
These are ramps and they make a great pasta sauce (more a ramp pesto).  They are also great in omelettes.

OK.  So what do ramps have to do with Chicago?  Well, according to a few sources, they are probably the reason for the city's name.  The Potawatami word for wild onions (also skunk but we'll ignore that variation) is
 Checagou.   Apparently there were a lot of ramps growing here in the "old days" and the area had a distinct aroma.   One of the 
Riverwalk Murals memorializes the impact ramps had on Chicago (the ramps are at the top of the mural, above the boat).
