For all but seasoned grill masters (who prefer to cook over wood or charcoal and to judge for themselves when food is ready), the Lynx SmartGrill (lynxgrills.com) may prove a welcome cooking companion. Guided by user preferences and hundreds of preprogrammed recipes, the SmartGrill’s onboard operating system syncs with smartphone and tablet apps to tell the cook with Siri-like voice prompts when to flip food and take it off the grill. The infrared burner—powered by propane or natural gas—allows for quick changes of radiant heat, while stainless-steel grates ensure high surface-heat retention. The SmartGrill (from $6,000) is available in 30-, 36-, and 42-inch grill widths.
