Due to always living in small nyc apartments i have learned to make the most from the fewest kitchen items.
I have a microwave now, i didn’t for more than a decade, but i really just use it to defrost soup or reheat my tea.
Otherwise i have:
An immersion blender (now 5yrs old from cuisinart, love it)
Breville juicer (i use 5-6xs a week)
Regular size blender (i seem to just use for summer smoothies)
Coffee grinder (critical)
Nespresso machine (a gift i use occasionally)
I use a stovetop Bialetti for coffee, and a kettle for tea water. I make toast in a skillet, and i have a manual mandolin for when i need to do uniform thin veggies. I wouldn’t use a slow cooker or rice cooker enough.
