How can I remove and keep away stubborn mould in a kitchen corner?

Mould normally forms due to a lack of heat / ventilation. In this case it sounds as if the room is warm and the tiles are cold and condensation is forming on the tiles.

Wash the mould away wiith a solution of bleach and water.

Next see if it is possible to keep a more even temperature in he room - additional insulation?

Extract damp air:- Perhaps get a small electric extract fan installed within the glass of a window in that room.

The above should resolve the issue as long as you use the fan esp when cooking!
