Rough chop the butternut squash, carrot, celery, and apple to help the blender.
Add all ingredients into the blender and blend until smooth. If you like a thinner soup, add more water until you achieve the desired consistency. Adjust the seasoning if it gets too watered down.
If you own a high speed blender:
Keep running the blender for about a minute and a half longer, until the temperature reaches 110°. Be sure to check the temperature with a thermometer in between so it won't go over 110°. Once it reaches 110°, transfer it into a bowl right away.
Top with cashew cream and pumpkin seeds (optional), and serve immediately.
If you don't own a high speed blender:
Pour the soup into a pot and heat it up on the lowest flame on the stove top. Stir constantly so you don't get a hot spot. Check the temperature carefully with a thermometer. Once it reaches 100°, turn off the heat and transfer into a bowl.
Top with cashew cream and pumpkin seeds (optional), and serve immediately.
Cashew Cream (optional)
Soak the cashews for 2-4 hours. Rinse and drain.
Add all the ingredients except for water into the blender and blend. Slowly add water until you achieve a smooth cream and no more.
Notes
If you choose to make the cashew cream for topping, make it before you make the soup.
Keeps for 3 days in the refregirator, stored in an air-tight container.
