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.

From chicken noodle soup to congee, no matter what cuisine or culture, what do you eat when you're sick? Since everyone around me is getting ill, I'm looking to expand my "sick food" recipes for drop off. Bonus points if it's easy on digestion and will keep in the fridge/freezer for awhile.

Chicken congee is my go to because it's simple and can easily be dressed up or down.

Thanks for all the replies! I love learning about different food (and beverages) so I hope you find something new to try yourselves.

I'm trying to change some nasty habits at the moment. My year's theme is self control, and beating addictions is a large part of it.

The symptoms I've been trying to fight off since last year: Snacking often, eating portions too large, eating past hunger/always finishing my plate even if I feel full, craving greasy fast food, craving sweets/sugar.

Progress is mixed. I'm trying a lot of things; I've reintroduced a 20:4 IF routine (my body is naturally somewhere around 16:8 - I never have breakfast) but I've had a lot of trouble obeying it for more than a few days.

I'm realizing, today, that one thing I have not really been looking at is the cravings. This HN thread is what clicked for me. I know that on a "healthier" diet, I crave very different things.

I'm looking at options on what I can introduce (gradually) to start getting my gut used to different classes of foods. I don't intend to switch to being vegan/vegetarian, I'm just looking to stop craving fat, salt, and sugar.
Or rather, not necessarily crave, but "if I see it I want it" kind of thing. I want to be able to look at a packet of crisps and think "blergh" by default, even if I'm hungry.

What advice I am looking for: Suggestions on snack replacements, juices, various tasty meals etc; things I can actually go for from day 1. I am not looking to do any large swaps. I am also not looking for extra effort; right now, a 99 percent of my meals are either store-bought, microwaved, or restaurant/takeout. I don't cook because I don't enjoy it nor usually have the time.

Example: I've decided to introduce ginger shots to my diet, see if it'll help. I'm also going to try having carrots on-hand more often as I really like those.

Note 1: I am considering giving Hello Fresh a shot next month, since I've never actually tried it, but I'm lukewarm on what'll happen.

Note 2: Allergic to bell pepper; dislike eggplant, celery, zucchini.
