I really miss gravy and it is hard to find instant packets of gravy that don’t contain high FODMAP ingredients. So I have created a recipe for safe and tasty low FODMAP homemade gravy. It also freezes well, which means you can divide it into portions and use it at a later date.
Check that the cornflour (corn starch) is made from maize and not wheat.
Make sure you buy a leek that has long green tips (this is the low FODMAP part), as you can’t use the white/light green leek bulb (this part is high FODMAP).
