You must mean this one: http://www.epicurious.com/recipes/f...berry-Sauce-754

I think I used erythritol instead of sugar but didn't add much because I used semi-sweet chocolate chips instead of unsweetened chocolate. As always you have to be careful using splenda with chocolate because they just don't synergize well.

I'd be really scared to use sugar free chocolate because I never have good results trying to mix all non-caloric sweeteners with things that have a lot of chocolate.
