Pork tenderloin with apples

Heat the oil and lightly sauté the pork tenderloin together with the onion. 

When it has browned stir in the brandy or rum. Then add 2 cups of hot water where you have dissolved the vegetable stock cube, a little salt and pepper and let the meat cook over low heat. 

A little before the end (about 5 minutes) add the apples. 

Finally, dissolve the corn starch in a little cold water, add it to the food and let it boil for an additional 5 minutes stirring carefully so that it doesn't stick to the bottom.
