You can cook the two soups separately in two saucepans simultaneously, or make them one at a time, and re-heat the first one.
For each soup, melt butter into saucepan, over low heat. Add chopped onion and peppers. Sprinkle salt and MSG. Cook on medium-low, occasionally stirring for 6 to 7 minutes.
Add cream and chicken stock.
Yellow Pepper Soup - add seasonings of turmeric, coriander, cumin, salt, white pepper, MSG,
Red Pepper Soup - add seasonings of paprika, coriander, cumin, salt, white pepper, crushed Aleppo chiles, MSG.
Stir, bring to boil, stir again, reduce heat to low and simmer for 20 minutes.
Remove both soups from heat and pour one of the soups into the blender.
Let soup cool for five minutes, then blend until smooth.
With blender running, add Xanthan gum, LITTLE BY LITTLE. If you dump it all at once, it will clump.
Pour soup back into pot, or other container. Clean blender and repeat with the other soup.
Pour each soup into a separate pouring vessel that has a spout. I used two different 1 cup measuring cups.
With one in each hand, pour them simultaneously from separate sides of the bowl and they will meet in the middle.
Drizzle Crème Fraîche and sprinkle chopped chives.
