I’m a gadget queen. What do I use a lot: immersion blender, microplanes, mortar and pestle, herb cutting board with double bladed herb knife (mezza luna), digital scale, handheld mixer, cast iron frying pans, bread maker (which I use for dough only, bake bread in oven), food processor.
Things I have but rarely use: sous vide, air fryer (fan assisted oven does the same thing), vita mix (too big to leave out, too heavy to lug around.
