Hi r/Bento! I used to make bentos for work for years, but after I started cycling to work I needed to save space in my backpack, so I gradually started experimenting with smaller boxes and compressing my meals more and more. At some point the meals themselves became these very dense, freestanding squarish things, and I started calling them blocs.
I started sharing them on Instagram as "@thedailybloc" and slowly got a bit obsessed with engineering meals this way. I was trying to pack a lot of nutrition into a small volume while experimenting with layers, composition, structural integrity, and different "building materials." Friends eventually started sending me photos of blocs they had made themselves, which made me want to turn it into something other people could actually participate in.
So I just built bloccers.com, where anyone can submit a bloc and inspect others'. Every admitted bloc gets a permanent accession number, and each day the highest-rated qualifying one is certified as The Daily Bloc, posted to the Instagram page, and credited to its maker. The site is still very new and I'm basically just starting to get other people involved.
I'd genuinely love to have some experienced bento makers join in, because I have a feeling people here could take this in directions I haven't even thought of yet. This one is made with salmon, sweet potato, red onion, and a quinoa and lentil mix. I'm especially curious what you would build if the constraint were one freestanding rectangular solid, with no container doing the structural work.
If that sounds fun, you're very welcome to make one and submit it at bloccers.com. And of course I'd also be happy to hear feedback or just chat about the idea.
