When my head isn't buried in a good reference book on cooking, I research about food on the internet. Here are sites and articles I found especially helpful and factual. And they make good reads.
Learn the Science Behind Cooking Good Food:
America's Test Kitchen. The second most valuable cook books I've ever purchased are from this company.
Why Food Date Labels Don't Mean What you Think, a PBS article: "Expiration dates are about food safety. Best before dates are about taste, texture and appearance."

Spices Inc.com has an extensive list of the types of spices, blends and herbs with descriptions. This is an online site for purchasing spices. And no, I'm not affiliated with the company and yet to purchase from them. Currently, I can purchase from a specialty spice shop in my location. I encourage you to look for a spice shop in your area if for no other reason than the adventure of visiting a spice shop, experience the aroma of so many spices, and learning about them.
What's Cooking America, History And Legends Of Favorite Foods - Food History If you're not a food wonk, this site may make you one! Linda Stradley gives you the history of foods and dishes in America and not just with dates and some historical references. You also learn about foods and dishes found in literature, such as Herman Melville's extolling the chowder in Moby Dick. On doing some research on clam chowder, I was reminded to what extent people will go to even legislate a dish: "1939 – In February 1939, a bill was introduced by Assemblyman Seeder to the Maine legislature to make it a statutory and culinary offense to put tomatoes into chowder." Seems quite laughable given the palate adventures of today's food pornographers.
