Chili is the consummate recipe for a crowd. Chili tastes even better the next day after the flavors have had some time to meld together. Be sure to make a big batch that will leave you with plenty of leftovers. (It freezes well too). A low and slow cook time—at least an hour total—is key for drawing out the most flavor in a pot of chili. Yes, a quick chili is most welcome on weeknights, but it won't have quite the same results.
Browning = flavor. Before you add any liquid to your chili, make sure your vegetables (onions, bell peppers, garlic, etc.) are softened and the meat (ground beef, turkey, short ribs, or chicken) is well seasoned and browned on the outside. The meat and vegetables will continue cooking once you add the liquid and let the chili simmer.
Aromatic, toasty spices are the foundation of a great chili recipe. Whole spices pack the biggest flavor punch. Toast whole spices in a dry pan until aromatic, then grind them in a spice grinder. If you're using ground spices, give them a sniff before using them—especially if you can't remember when you bought them. Ground spices lose their potency after about six months to a year.
We know Texans will call this blasphemy. For the rest of you bean lovers out there, choose wisely. Kidney beans are a popular choice because they are large enough to stand up to the other ingredients. Black beans and pinto beans are also good options. Avoid small white beans, which can break down and get lost in the mix.
