A little help, please

PP handed me a recipe, it calls for butter blend and sanding sugar.
 
I'm thinking butter blend is butter and margarine mixed, what proportion? Can I just use butter?
 
What is sanding sugar? Can I use regular granulated?
 
Thanks y'all!

I have found that i can use butter instead of a butter blend-although butter burns more easliy so that is why recipes suggest using it. Land O Lakes sells a butter blend. Sanding sugar is generally the pretty colored sugar used in holiday baking-I have seen it in just plain white crystal. I suggest you dont use regular granulated. What are you making?

Yeah, sanding sugar is the coloured kind you use for decoration.  It's bigger crystals than regular granulated, so I wouldn't use regular either.
 
As for the butter blend, I suspect in a bread pudding it's more for trying to make it healthier rather than anything else.  Good bread pudding pretty much requires real butter, but that might just be me.  Usually what they mean is a mixture of butter and margarine like the "spreadable" butters.  I find them to taste like plastic, but you could probably create your own...it's usually 50/50.
