What was somethings you learned from cooking shows?

I learned from the show Culinary Class War that if you boil noodles and let it cool down on a baking sheet, the wide surface area helps it cool down faster than in a colander. Also from the influencer MadebyMusashi that a bain-marie filled with water can be used as a spoon rest that also cleans it while you’re cooking.

I’d like to know what tips or techniques you learned from cooking shows or even cooking influencers that you use now.
