Add olive oil to the pressure cooker.
Immediately add garlic so that it can get heated along with the oil. This way the flavor is really enhanced.
After the aroma arises, add onions and saute till translucent.
Add broccoli florets, stalks, almonds, vegetable broth or water, 2 pinch salt, sugar and mix well.
Close the lid and pressure cook for 2 whistles. After the pressure releases by itself, open the lid.
Using an immersion blender, blend the soup well.
If you do not have an immersion blender, let the heat come down a little. Transfer to the blender jar of your mixie, blend till smooth and return to the cooker.
Switch on the stove and simmer the flame completely.
Mix in almond butter, if using, add salt, pepper and let it boil till you see small bubbles on top of the soup.
Switch off the flame.
Serve this broccoli almond soup piping hot topped with almond slivers.
