If I was going to start my own tech site or media vertical, with no intention of turning a profit or even being all that knowledgeable, I'd do food gadgets. I won't shut up about the Instant Pot, I own a sous vide machine (that I now have a guide for) and the contents of my kitchen drawers are the equivalent of the crying face joy emoji. The festive season and the epic-scale meals that accompany it make it a peak opportunity for simplifying your established cooking norms, but it's also a gamble. My mum has an Instant Pot, sure. Will she use it for sauces or sides for this year's Christmas dinner? Probably not. It's about consistency. She's cooked more Christmas meals than I've had... Christmas meals. I'm not going to suggest she shake things up.
The best kitchen tech is simple. I own a Nespresso Barista milk frother. It can heat and whip up milk, making at-home flat whites a possibility. Is it smart, though? It has Bluetooth connectivity and a companion app, but besides downloading new recipes (more or less milk; hotter or colder) that's not remotely necessary. It makes silky milk for my latte nonsense, though, so it keeps its place on the kitchen worktop. Crucially, the metal jug and magnetic stirrer are both incredibly easy to clean -- something all kitchen gadgets could benefit from.
