I live near Boston but have a friend in Madison, WI. She started sending me Kodiak Kakes flapjack mix for my birthday when she lived in Alaska, and can get it in Madison too. She asked me if there were any midwest specialties that I'd like her to include. I have no idea what sort of non-perishable foods are available in Madison but not New England. I do not care for smoked foods, or very spicy ones, and am vigilant about limiting sodium. My ancestry is northern European so I grew up meat-and-potatoes but I have branched out and enjoy most cuisines. I love onions (all alliums, really), fruits, and sweet&sour things.
Can anyone suggest things I might like that can withstand 3-4 days in the mail?
