In the past few months I have been reading a lot about historical food culture. It's kind of amazing how much things have changed here in the US. Over the last century or so we have basically eliminated communal eating and massively changed the economics of prepared meals. At one point we had automats and cafeterias which skipped out on most of the "front of house" service and focused on serving large volumes of people to keep prices low. There were also diners, which are much different from what we consider to be a diner today; they were very small places that only prepared simple things that needed very little labor to prepare; things like hash browns, sandwiches, or pancakes, so the food was still very cheap. But because they were small, they were able to serve smaller markets that other restaurants were not able to capitalize on. Compare that to today, where diners are just restaurants that have 50s style decor.

But the thing I think is much more unusual is how rare we see food used in service of a message. It's something that has a long history across the globe. Most notably, religions operate food kitchens that help to bring poor people into their folds. Some religions actually have a built-in food culture that includes feeding your neighbors. It's really effective too; there's a small chain of restaurants where I live that has inexpensive food which has some bhuddist texts at the dining tables, and honestly it had me considering joining a religion for the first time. If I spoke Chinese they might have got me! Eating food requires a baseline of trust, so if you can get someone to eat at your restaurant you will bypass a lot of the caution that people approach the world with.

With that being said, why isn't food-based activism a lot more popular? I'm sure that it would work for much more than religion. A restaurant that acts as a messaging platform doesn't necessarily need to be funded by food sales, so they can undercut the competition on price and reach an even greater audience. Given the ways I have seen religions use food to further their means, I think that it could even go farther than changing people's minds about topics and actually motivate people to take action and join communities who are actually making real change. Food is both relatively inexpensive and it's something that everyone needs to survive, so it seems to me that food-based activism is the single largest missed opportunity for community organization.

There are many tips or techniques that are strongly recommended for cooking, but it's hard to know which are evidence based and which are just passed along because that's what people always do.

Which are the tips that need more evidence?

Here are two that I struggle with, about stainless steel pans:

1. Water drop test / leidenfrost

People say that if you get your pan hot enough to get the leidenfrost effect and then add the oil you'll have less problems with sticking. My problem with this is that it means the pan gets very very hot - much hotter than it needs to be for most uses. My other problem is they all say "Look, I'll cook eggs and they won't stick" and those videos either have a ton of cuts, or the eggs stick and you can see the person pushing with a spatula to get rid of the stick, or their "scrambled eggs" is really a chopped omelette.

2. Heat the pan before adding oil. I don't understand this. Again, people say it helps prevent sticking, but they use some argument about "pores" which just feels hokey. I add cold oil to a cold pan and bring it up to temperature before adding food so the pan and oil are both at the right temperature, and food sticks and then releases, because that's how stainless pans work.

I'm aware I could be completely wrong here and that there may be a good evidence base for these, but they don't seem to work based on how I cook.
