Low Histamine Vanilla Alternatives

If you are histamine intolerant and following a strictly low histamine diet, you should be avoiding vanilla in all its forms.
Just for variety, try one of these vanilla extract alternatives. There will of course be changes in flavor, but they will be subtle.
Maple syrup—replace the vanilla with an equal amount of maple syrup.
Natural, oil-based, alcohol-free caramel (or cardamom) essence. Swap the vanilla for an equal quantity of these flavorings.
Molasses, golden syrup, honey, brown rice syrup or treacle may provide an acceptable vanilla substitute.
Recipes for apple caramel, coffee essence and more are included in the book Is Food Making You Sick?
