Not sure why you want a blue sauce but might help.....
Why not? Being creative helps pave the way for more ideas.
I know it's more of a novelty but this attempt I did was pretty hot. I'll never actually produce it because I refuse to sell something using HF Corn Syrup:
This was made by taking 1/2 gallon mason jar, filling it half full of
Berry Blue Typhoon Hawaiian Punch concentrated shaved ice flavoring and packing it to the top with Red Scorpion peppers, that were halved.
I let it infuse for 6 months, strained out the chilies, and put them into a press and squeezed any extra juice out of it. Milled out the seeds, added it to a pot, added a tad more corn syrup until it had the desired consistency and called it a day. The chilies had changed from red to purple (I discarded these), and the result was pretty friggin hot. I couldn't find much use for it though other than to put it on vanilla ice cream, it was too hot to eat on anything else and the blue color didn't mesh well with anything, not to mention probably not good for you either, being 98% dyed HFCS and probably 2% capcasin oil.
It's fun to make, but I couldn't think of anything applicable to pair it with, and now I have a case of 5oz bottles that I'll never use just sitting on a shelf collecting dust. A conversation piece at best.
Blue doesn't really happen in nature too often, and I can't think of a truly chartreuse colored food that naturally occurs. Heinz tried this a while back with purple and green ketchup. It tasted the same but aside from kids, no one bought into it.
