Surplus tomatoes??? I wish! I'm coming off a decade-long tomato famine. Just like the one that sent the Irish streaming into America in the 1860s.
Concerning ketchup: I will say this--I remember one of my high school buddies had an aunt that made homemade ketchup. It was outstanding. There was a noticeable taste of cinnamon in it. She also taught him, and he taught me, to drink pickle juice. That was a game changer for me.
Then there was his uncle Carrol. He grew what was then known as K-weed. I never partook, but some of my classmates looked forward to the harvest. One, who is now a pastor ... well, I've already said too much.
On another topic...fresh tomatoes are great, but canned tomatoes are available all year and they're consistent. Below ness utilized them to make a simple marinara with olive oil, diced onion, sliced garlic, salt, sugar, red wine, red pepper flakes and canned crushed tomatoes. Served over ho'made spaghetti (boil water, add salt, open box, drop in dried pasta, boil for a while).
