• Cauliflower Stem Hummus


Many cauliflower recipes call for the florets, but what about those perfectly edible cauliflower stems? Rather than throwing the stem (a.k.a “core”) in the compost, you can make this caulfilower stem hummus for zero waste cooking and a nutritious snack! The stems from one cauliflower head will only make 2-3 servings of hummus, but you can save and freeze stems until you collect enough to make a decent sized batch, ideally 2-4 stems.

  • 1 teaspoon cumin
  • ¼ teaspoon salt, more to taste
  • 1 clove garlic
  • 1 teaspoon dijon mustard
  • 1½ Tablespoons tahini (or substitute more oil)
  • 2 Tablespoons lime or lemon juice
  • Up to ½ cup of water, as needed
