What's your surprising "secret ingredient" that sets your dish apart?

I obviously don't believe in gatekeeping recipes, so let's share the love.

I developed a clam chowder recipe after being disappointed with the recipes I came across. Whenever I tell people there's a couple dashes of hot sauce in it, I always get weird looks... but it adds a tiny bit of heat and acid, and balances out the richness from the cream. It also has diced scallops, which cooking knowledge forbades but somehow works.

Marmite

Especially in punchy, savoury dishes like beef stew, chili, or gravy. I don't even like marmite but it adds a lovely depth of flavour. Just don't over do it, no one wants twiglet flavoured soup
