Hi Jayne, welcome!

I'm not Karen, but I can help you with this one. Canadian Sugar Twin is the brand name for sodium cyclamate - not available here. We can substitute with Splenda - either granular or tablets. Tablets have the great advantage of being almost devoid of carbs whereas granulated Splenda has 24 carbs per cup.

All the best to you matey. And do check out our Aussie/NZ forum.

PS: Sugar Twin is "spoon for spoon" the same as Splenda, so Splenda can be directly substituted. The tablets as you probably know are each the equivalent to 1 teaspoon sugar, so for North American recipes, 48 tablets = 1 cup sugar.
