Prepare the Broccoli: Trim about 2cm off the woody base of the broccoli stems. Pull off any coarse outer leaves, but keep the smaller, tender ones attached.
Toast the Seeds: Place a dry frying pan over medium heat.
Add the sesame seeds and toast, shaking the pan, for about 30 seconds until fragrant and golden. Immediately tip them into a small bowl to prevent burning.
Heat the Whey: Pour the whey into a saucepan and bring it to a gentle simmer.
Poach the Broccoli: Carefully add the prepared broccoli to the simmering whey. If the liquid doesn't cover it, add a splash of hot water.
Simmer for 3 minutes until tender-crisp.
Serve: Using a slotted spoon, transfer the poached broccoli to a serving dish.
Sprinkle with the toasted sesame seeds, sea salt, and pepper.
Finish with a few knobs of butter or a generous drizzle of olive oil.
Don't overcook the broccoli.
Keep it tender-crisp for the best texture, vibrant color, and nutrient retention.
