A question about a recipe: Paul Bertolli's Cauliflower Soup
I have a question about step 2 on the recipe "Paul Bertolli's Cauliflower Soup" from Genius Recipes. It says:
"Add the cauliflower, salt to taste, and 1/2 cup water. Raise the heat slightly, cover the pot tightly and stew the cauliflower for 15 to 18 minutes, or until tender. Then add another 4 1/2 cups hot water, bring to a low simmer and cook an additional 20 minutes." For the 20 mins at low simmer, do I cover the pot or leave it uncovered?
