cook the noodles until soft. drain them and let them cool off. I put mine in the fridge after rinsing with cool water. I also stir them with a spoon every so often

take out the cheese blocks. slice into small squares. cover stick in fridge

rinse and cut up the celery. cover and stick in fridge. Rinse and cut up anything else you want to add , including onion.

with the vinegar and sugar you can add a beaten egg. I dont notice a difference and don't add this but my mother does. don't let the egg make chunks. stir it in whisking constant to avoid that. make sure it is cooked though

take out the cooled noodles. mix in the vinegar and sugar mixture

add in cheese and mix this all up

add mayonnaise and a small amount of mustard. I add in about 2 to 4 teaspoons

mix well. taste. you can add extra vinegar, sugar and mayonnaise. add more salt or pepper if needed or wanted
