  • 2 tbsp extra virgin olive oil
  • 1/2 tsp freshly cracked black pepper
  • 1 tsp kosher salt

For the Sauce:

  • 2 tbsp salted butter

Soaking and sprouting replicates germination, which activates and multiplies nutrients (particularly Vitamins A, B, and C), neutralizes enzyme inhibitors, and promotes the growth of vital digestive enzymes.

How do you get the bitterness out of brussel sprouts? ›

A splash of lemon juice, or even apple cider vinegar, works wonders on bitter sprouts. Another key ingredient is fat, which helps Brussels sprouts to crisp up. This is why it's so popular to render bacon fat and cook Brussels sprouts in it, then add the bacon bits back in at the end.
