I figure most people on Chefsteps are somewhat plugged in to internet-cheffy types in general. I made Alex (the french guy)'s version of Luciano Monosilio's carbonara last night to resounding success. I've made plenty a tasty carbonara in my day, but the double boiler / hollandaise approach to making the sauce really did yield the best results I've had. One thing I never really loved about making carbonara was the somewhat sensitive timing, having all the parts ready at the right time, using a whole bunch of burners at once, things that make me focus on the food and not the party, basically. Anyways...
My mind immediately went to the hollandaise I make with Joule, as part of the benedict recipe. It would be super fascinating to see if there is a water + wheat starch + egg + cheese joule make-ahead ultimate carbonara sauce experiment here. Grant? Nick?
