Reminds me on viral videos about "100 hours recipe" where someone tested some of it and to their surprise, they actually taste good (unlike a lot of viral recipes that's mostly just clickbait). Most of it is basically just leaving the ingredients marinating for a day or two in the fridge. My problem is more that, who have the foresight to think "I want to eat brownies/steak/whatever in 3 days, let's start now."
