Strain the beans and add them to the pot along with the beer, syrup, tomato paste & pepper. Stir it together and then close the lid and then set the machine to the pressure cooker for 35 min.
Let the steam escape and check the beans for doneness and that there is enough liquid still in the pot.
Continue cooking 5 min if needed.
