Blend almond milk and pear in blender until smooth.
Add the oil to a pot on the stove and heat it at medium to high heat.
As the oil heats, sift the flour and add to the pan stirring vigorously.
Fry the flour in the oil for around 3 minutes, stirring the whole time, don't allow it to get too hot, turn down your heat if it starts to stick at any point.
Add the almond milk and pear mixture.
Continue to stir and allow the sauce to gradually thicken. You will usually get to the right thickness after it has reached boiling point and boiled for a few minutes.
When you've reached the desired thickness (keep in mind that the sauce will continue to thicken as it cools), remove from the heat and add salt and pepper as well as any other spice you prefer.
