My husband and I love this recipe. I would like to double it for a family get together-but I am confused. When I hover over the 2x it doesn't increase the amount of broccoli or cauliflower?? Is this correct?

Two more things: I steamed my veggies for 8 minutes and they were perfect. I also looked online and what I read was that it's about 5 cups of broccoli and cauliflower so that's what measurement I used.

I made this last night, adding the onion as someone else suggested. I totally forgot the heavy cream and added some garlic powder and a little Greek seasoning. This was the best recipe!! It's definately a keeper and one I'll be making often.
