By far the best bacon-related novelty is Skillet's Bacon Jam (they're a constantly-moving burger "cart" here in Seattle). It's cooked down with onion and seasoning and ground only just smooth enough to be spreadable. It's like Vegemite/Marmite spreads in that it's an easy way to add a savory/umami flavor to anything, but infinitely better because the flavor is concentrated bacony goodness. Spread atop their magnificent burger, it's truly home, but it works on anything that would benefit from bacon flavor (read: anything). Bacon Salt is the only other product I've tried that's actually at all satisfying, especially on popcorn. Everything else, well...it has real bacon to measure up to, and that's no short order.
