As promised, here is my recipe for creamy cauliflower puree. I've made several different/ similar recipes, and this is by far the most delicious. I originally found the recipe here, and I pretty much stick to it, minus a tweak here or there.
You can make and eat this puree with anything that you would normally serve with mashed potatoes. Just know that the consistency is smoother and looser than the typical mashed potatoes.
Creamy Cauliflower Puree
1 medium-sized head of cauliflower, cut off the florets
2 scallions, whole
3-4 garlic cloves, whole
1/3 cup buttermilk
1 tbsp. butter
Fill a large saucepan a little less than 1/2 way full with water. Add the cauliflower florets, scallions, and garlic cloves, and bring to a boil. Turn the heat down to medium, put the lid on the pot, and allow the cauliflower to cook until fork-tender.
Drain the cauliflower, scallions and garlic, and add to a blender. Once the florets are almost completely pureed, add the buttermilk, butter, and salt and pepper to taste. Blend again until completely smooth.
Serve immediately. Yum.
