Your recipe seems to be missing tomatoes (assuming you weren’t going for an onion ketchup?).

it is. I willingly gave a variant to do in the absence of tomatoes. You can add them and get a more proper ketchup (I wrote optionally add tomato sauce, but it's true most people call ketchup only what has tomato in it. To me, the taste is quite similar even in the absence of tomatoes, what really gives the ketchup signature taste, again my opinion, is the balance of vinegar/sugar).
