Ketchup
Ketchup is low in purines and generally safe for people with gout in normal portions. A typical 16 g serving has about 2 mg of purines, under 1% of a ~400 mg working daily target. It also carries about 1.4 g of fructose per serving, which raises uric acid on its own.

How much can I eat?
Added fructose raises uric acid on its own, so keep sugary foods and drinks small.
How we count fructose
This is the fructose, not the total sugar: it counts free fructose plus half of sucrose, so a sucrose-sweetened product carries roughly twice this much sugar overall.
Evidence: Ayoub-Charette et al., J Nutr 2021 (fructose by food source) · White et al., Am J Clin Nutr 2018 (whole apple vs. a fructose drink, matched dose)
Purines are not the limit here: even a large serving stays well under a day's purines. The sugar is what climbs with the portion.
Only part of these purines counts toward gout: the 2 mg here counts as roughly 1 mg toward your gout risk.
Ketchup is an easy choice to keep on hand.

Added fructose raises uric acid as your body breaks it down, even when the purine number looks low.
Per 100 g and processing
Per 100 g (for comparison)
Low for gout (< 50 mg/100g).
High for gout (8–15 g/100g).
Processing: NOVA 3 of 4 (processed food). How processing affects the grade.
Diet is part of the picture, not all of it
For most people the body makes the majority of its own uric acid. Food contributes the smaller share. Eating well lowers your risk and helps you feel in control, but for many people diet alone does not bring uric acid down enough to stop flares. Medication often does the heavy lifting. Use these grades to make easier daily choices, and work with your doctor on the full plan.
