Lighter fluid is fun to play with, but it can impart an off flavor to your food. A chimney starter is faster, cleaner, more efficient, and better for the environment. It's a tall metal cylinder with holes punched in it and a grate at the bottom for holding the charcoal. It works with the power of convection: When a lit newspaper is placed at the bottom, igniting the lowest coals, the hot air rises up, pulling fresh oxygen in through the vent holes and through the bottom. This constant supply of fresh oxygen, coupled with the fact that the metal efficiently reflects heat back toward the coals, means you require nothing more than a single piece of newspaper and a match to turn a full six quarts of coals into a roaring inferno within 20 minutes.
Grill brushes come in all shapes, sizes, and styles, but for a tool that sees so much use, I find it hard to justify spending a huge amount of money. This simple, heavy-duty wire-style grill brush has served me well for years, and if it ever wears out, well, it's cheap enough to replace.
Single-use wooden skewers are just fine if you only rarely cook meat-on-a-stick, but if you kebab your dinner more regularly, a set of sturdy reusable skewers is a sound investment. I like to use flattened metal skewers, which prevent vegetables and meat from rotating as you maneuver them on the grill.
There's form, and then there's function. The aprons from Tilit are great on both fronts. Made from waxed cotton, they offer breathability along with water resistance, but they're also damned handsome. Just like Dad, right? Right.
