Prepare your pressure cooker by setting it to the high saute mode for 5 minutes to cook your bacon slices.
Once the bacon slices are crisp, remove them from the pot and add them to a paper-towel lined plate; set aside.
Add the chopped garlic and onion and saute for about 3 minutes.
Turn off saute mode, and add the potatoes, corn, spices, and broth to the pot.
Set the pressure cooker for 15 minutes pressure cook time on soup mode. Your model may vary.
Make sure the pressure cooker cover is sealed and locked correctly, and the valve is set to airtight.
Your pot will take a few extra minutes to get up to the pressure needed to cook. These times vary and are not worked into the actual cook time.
Once soup is done being cooked, allow pressure to naturally release.
After pressure is released, carefully open the pot.
Add flour to milk and microwave for 1 minute, whisk thoroughly.
Turn pot to saute mode, and add in milk and flour, stir until mixture is absorbed.
Cook for an additional 2-3 minutes.
