Rice syrup

Rice syrup is made by breaking down rice starches into sugars — a simple process with no fermentation or aging.

• Why it tends to be fine — the production process doesn't involve anything known to generate histamine, and rice itself is generally considered low risk

• Compared to other syrups — rice syrup is often used as a corn syrup alternative; both are similarly low risk from a histamine standpoint

It's a straightforward option if you're looking for a minimally processed liquid sweetener.
