You could try vanilla essence – adds a sweet taste, or stevia sweetener or maple syrup or apple sauce – just beware the calories! Think they would only add about 5 calories or so!

Hi SairyG cinnamon does have a few other benefits besides taste and stabilising blood sugars it also helps control blood pressure and mildly anti inflammatory and is also a source of bit K, iron calcium and magnesium. However, am with you, taste, dodgy! Best of luck.

jilli72 and Radroa thank you for clearly stating the benefits of cinnamon for SairyG and updating the little research I had on the subject. I was looking at the idea that the porridge would only be eaten on a fast day so then the health benefits would have little impact. For me, I like cinnamon toast- delicious. Remember that for some, probably only a minority there could be some minor irritations.
Good luck Sarah.
