Rising ingredients?

[Joan Benner 0]

Are baking powder or baking soda allowed?

[SugarcubeOD 3974]

Yes but not to recreate baked goods which is what I think you mean by 'rising' ingredients?

[ShannonM816 5307]

Baking powder sometimes has cornstarch which isn't compliant, so you'd need to read the label. Not all brands do, but some do.

If you need baking powder, a combination of baking soda and cream of tartare will substitute (noting the restriction on recreating baked goods). I used this when making a cake during reintro which only had sugar as a non-compliant ingredient.
