As someone who loves to cook I think kitchen advances are somewhat
overlooked, from pressure cookers to microwaves to air-fryers, IR
ovens and all sorts of amazing combos, hand blenders and whatnot Time
to make good home food got much shorter and more energy efficient.
Edit: showing my age, cos that's 80s, not 90s. In fact I think pressure cookers got popular in the mid 70s.
