Is xylitol safe around pets?
No. Xylitol is seriously toxic to dogs even in small quantities. Store it out of reach and do not give them anything baked with it.
Can I swap sweetener for sugar one-for-one?
Erythritol and xylitol come closest and are the usual starting point. Stevia does not - it is far sweeter by weight and needs something to make up the bulk.
Why does erythritol taste cooling?
It absorbs a little heat as it dissolves, which registers as a cool note on the tongue. It is more noticeable on its own than in a finished bake.
Are these suitable for diabetics?
Sugar alcohols and stevia affect blood glucose less than sugar does, but if you are managing diabetes please take dietary advice from your GP or diabetes nurse rather than from a product page.
