Why they work

Almost everything ketchup carries, sauce has too: 45 of ketchup's 45 flavor molecules also occur in sauce. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy).

What each one brings

ketchup

The tartness. Sour notes make up 35% of its labelled aroma molecules, against 33% for sauce. Every molecule it carries is also in sauce.

sauce

The caramel side. Caramel notes make up 2% of its labelled aroma molecules, against 0% for ketchup. It carries 3 molecules ketchup doesn't have.

Recipes with ketchup and sauce

We have no browsable recipe that lists both ketchup and sauce.

Can you swap one for the other?

Fairly well, for flavor. Each carries most of the other's flavor molecules (100% of ketchup's and 94% of sauce's are shared). This compares flavor only; texture, moisture and the job each does in a dish matter too.
