I love squash especially acorn squash and butternut squash. If i'm being honest there isn't much I don't love, food-wise that is, and my favorite cooking season is fall. The weather starts to cool down from the long hot summer and it's time to start making all those wonderful fall and winter comfort food dishes like soup and short ribs and pot roast. Just thinking about them makes my mouth water.
Squash soups are some of my favorite soups to make, especially roasted butternut and roasted acorn squash soups. Their deliciously creamy texture gives them a wonderful feel, they are so versatile they pair well with a lot of different ingredients, and the flavor is amazing.
This acorn squash recipe is particularly nice. It has a slightly sweet flavor from the apple, pear, and brown sugar but it's balanced nicely by the acid from the wine, vinegar, and lemon.
When the soup is done puree it in a blender. Working in batches, fill the blender bowl about a third of the way. Add about a fourth of the yogurt mixture to the soup. If you add too much hot liquid the pressure is going to be so strong that it may blow the lid off even if you are holding it on. Place the lid on the bowl and place a folded kitchen towel on top of the lid. While applying firm pressure to the lid, via the towel, turn the blender on to the lowest setting. If you just hit "High", instead of starting with "low" and gradually increasing the speed to "high" the pressure is going to be so strong that it may blow the lid off even if you are holding it on. Then increase the speed until it is on high. Puree until you have a smooth homogeneous liquid. Once the blender gets going the pressure isn't as bad.
When you puree hot liquids the blender builds up pressure from the heat and blows the lid off spraying hot soup, or whatever you're pureeing, all over the kitchen and you, resulting in one big mess. Not only that, but it can cause burns, sometimes very serious burns.
When I was a line cook I made some butternut squash soup. I must have had 5 gallons of soup to puree. I went over to the blender, blissfully ignorant of the physics involved with pureeing hot liquids, and filled that baby up, about an inch from the top. By the way, this was a large commercial blender with a 1 gallon bowl and a 5 horsepower motor. I think that thing could have pureed rocks.
So soup loaded, blender on high!!! Soup on the windows, back door, counters, floor, ovens, cooling racks, the pastry guy, me, everywhere. Man, that stuff burned. It was in my ears, nose, eyes, hair and all over my clothes. Don't lull yourself into thinking it was because it was a commercial blender, I've seen others repeat the folly with a household kitchen blender.
