I recently learned about Edible Alchemy, a Chicago-based food exchange program founded by SAIC alumni in early 2009. Here's their mission statement:
"Edible Alchemy is a catalyst for the creation, expansion, and connectivity of a vibrant food community. We organize open discussion and potlucks, distribute local organic produce shares, offer volunteer opportunities, and provide for community-related events. We believe that nutritious food is essential to the healthy individual and to healthy shared environments."
You can pay $20 to receive a box of a combination of local fruit and produce. The contents of the boxes depends on what items are in season. Although a delivery service isn't available, the boxes contain enough items "...to fill your kitchen with fruits and veggies for about 2 weeks for 2 vegetable lovers cooking 3-5 meals a week."
In addition to participating in the fruit and produce share, dry bulk, homemade baked good, dairy products and eggs are available for purchase.
