Preparing potatoes
Peel the potatoes, cut them into cubes and steam them until they are completely soft.
Puree
Mash the potatoes with a potato masher or push them through a food processor until smooth.
Mix
Add the egg yolks, diced butter, a good pinch of salt, and a little pepper if desired. Mix well until smooth and firm.
Forms
Fill a croquette press or piping bag fitted with a round nozzle with the mixture. Pipe long sausages onto a baking sheet lined with baking paper. Cut into even pieces of about 6 to 7 cm.
Cooling
Let the croquettes stiffen in the refrigerator for at least 4 hours.
Breading
Coat the croquettes successively in flour, beaten egg white, and breadcrumbs. Place them on a plate sprinkled with breadcrumbs.
Frying
Heat the frying oil to 180°C (350°F). Fry the croquettes in small batches until golden brown and crispy. Drain on paper towels.
Tips
- Work cleanly and cool to obtain nice croquettes that do not burst open.
- You can also freeze the croquettes for use at a later time.
- Want extra creaminess? Add a knob of extra butter.
- Make them ahead of time and bake them à la minute for ultimate crispiness.
