Food that is actually spicy. I know it is available at some locations on earth, but I do not live within 500 miles of any of them. The only place near me that even offers a legit hot sauce is a food truck and that one is still a bit tame.
I’ve never seen sourdough French toast at a restaurant and it is literally the best bread to use. The texture holds up well to the egg dunk and the funky sourness complements the otherwise cloyingly sweet dish. Even better, instead of syrup I use salted irish butter, making it a savory dish with a hint of sweet cinnamon.
Undersink filter with a dedicated drinking water tap. Removes the chlorine taste that is probably what makes you think salty. You can get the whole setup for $75 and install it yourself. The filters are $40ish and last 6-12 months.
Some fridges have cold filtered water taps built in.
