• Step 1

  Heat water, lemon juice, and 1 tsp salt in large pot on HIGH. Bring to boil; add cauliflower. Return to simmer; stir. Reduce heat to MED-LOW; simmer, 20 min, until fork tender. Transfer cauliflower to colander (reserve 1/4 cup cooking water); let drain 10 min.

• Step 2

  Add reserved cooking water, half the cauliflower, and 1 tsp salt to blender; puree until smooth. Remove 2/3 of puree from blender; add remaining cauliflower to blender. Puree until smooth; combine batches.

• Freeze unused puree for future use. • While pureeing, stop to scrape down sides of blender. • Depending on blender size, this may have to be done in more than 2 batches.
