Everyone’s Favorite Low-FODMAP Tomato Ketchup Recipe; Gluten-free, Vegan

Printer Friendly Version

Ketchup is an American staple.  What kid doesn’t slather their french fries in about 10 packets of the stuff?  I know I did.  So the size of a low-FODMAP ketchup serving is a bit tough to take.  Plus, I prefer to make my own to incorporate organic ingredients and my desired level of sweetness.

Here is a delicious, savory low-FODMAP tomato ketchup that is sure to please kids and adults alike.  You can also put it in a small container or bottle to be able to take it on-the-go!  Super easy.
