Why they work

More than half of ketchup's flavor molecules (28 of 45) also occur in roe. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy).

Recipes with roe and ketchup

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

Can you swap one for the other?

Not really. Each has a lot the other lacks: roe has 18 molecules ketchup doesn't, and ketchup has 17 that roe doesn't. Treat them as partners, not stand-ins. This compares flavor only; texture, moisture and the job each does in a dish matter too.
