This is embarrassing, but I may as well ...
I should say, I cook every breakfast and dinner, and 90% of lunches (my husband and older teen eat out occasionally).
At least daily: Toaster, Electric kettle, burr grinder, french press (not really an appliance), fridge, range, microwave
Every few days: dishwasher, oven, grill (just out the back door), stick blender, blender (for smoothies), hand mixer, popcorn popper (for after-school snacks), chest freezer
weekly-ish, depending on season: Slow Cooker(s), pressure cooker, food processor, rice cooker (was a gift, I don't like rice that much)
Monthly? Big 'ole kitchen aid mixer, waffle iron
There are a few baking things (roasting dishes and such) that get used only a few times/year, but we remodeled to have a ton of kitchen space, and there's room for everything to fit gracefully. Also, many of these things were gifts and/or hand-me-downs.
Also, I should make waffles this weekend. Coincidentally, the sourdough needs to be fed...
