Select a pot and a steamer that fits it. Heat the water for steaming while you cut the broccoli florets. Place the broccoli florets in the steamer dish and zest the citrus onto it. Both orange and lemon are good. Then cut the citrus in half and squeeze the juice from one half over the broccoli. Sprinkle on the tamari, if using. The benefit is that you will then get some salt into the inside of the broccoli, whereas the truffle salt, added after cooking, will only season the outside. It's also easier on the budget since you will have to use less truffle salt. You can also sprinkle on freshly ground pepper at this time. When the water is boiling, place the steamer dish of seasoned broccoli on and cover; steam for 3 minutes or longer depending on how crisp you like your broccoli. I like it done almost to death so I go for 5-7 minutes. To serve: Plate the broccoli, sprinkle lightly with truffle salt, and place a little bit of the truffle salt in an small bowl on the table.
