The ten-minute salt purge. Tomatoes are over 90 percent water. Salting early pulls the surface juice off so the glaze stays a glaze instead of dissolving into a brown puddle.
Cheese at room temperature. Cold mozzarella straight from the fridge is rubbery and coats the tongue in dull butterfat. Warmed to the room, it releases its volatile flavour compounds.
Oil before vinegar. Laying the olive oil down first stops the dark glaze sliding off the cheese or staining it streaky.
Tear the basil, do not cut it. A blade crushes the leaf edge and triggers oxidation that browns the cut within minutes.
