New to Soda Making, Diet Soda recipe

[goldenphoenix11]

I am now getting into soda making and was wondering how to go about making a syrup with an aspartame/ace k base, I know aspartame breaks down over heat, so how would I go about making a syrup with that sweetner? Any recipes?

I mostly use Stevia to sweeten my diet/low cal sodas, but if you want to ise aspartame/ace k, you would have to do all the heating first (steeping flavoring ingredients, etc.) then let it cool completely before adding your sweetener. You could also try sucralose (Splenda), as it is not supposed to be broken down by heat.
