Imagining a recipe for tomato sauce, I thought…Why not, in concert:
Roast the tomatoes in the oven (Roma, if you please);
Roast garlic bulbs simultaneously but separately in the same oven;
Use a cream whipper to infuse drizzling oil with fresh rosemary and basil leaves;
Caramelize onions and shallots (yes, both) to their utmost sweetness and then puree/food process them for smoothness;
Finally, when the fragrances blend together, join the elements with a stick blender!
