Anyone else get addicted to making sauces at home?

This might sound weird, but sauces changed how I eat.
Once I learned a few base sauce formulas (creamy, spicy, sweet, herby), I stopped ordering takeout as much.
I’ll eat the same chicken or fries but switch the sauce and it feels like a new meal.
Low effort, big flavor upgrade.
Curious if others do this too?
What’s the one sauce you always keep in your fridge?
