Most recipes require simple steps and fresh ingredients
That is the thing, most restaurants in CT don't use fresh ingredients (too often out of season too) and don't make their food to order (always better when they start to prepare dishes only after the customer orders.)
Use fresh, IN-SEASON ingredients and you are already more than halfway there to having a great sauce, or any recipe for that matter, at home. The rest is just practice and fine-tuning and your outcome will, in not much time, be better than most places you go to eat out.
Threads like this are really reserved for the real upper echelon of restaurants, all of which have fresh, in season, made to order dishes, the top 1, maybe 2%.
