Use white pepper if you like, I love the flavour of freshly ground black pepper
Peel the potatoes if you want, unpeeled potatoes retain a nice bite to the potatoes and the peels have good nutrients, leave them unpeeled where possible
Use processed cheese if you do not have cheddar cheese
Add some finely chopped celery with onions if you want
Use fresh or frozen corn kernels. If using frozen, add them directly , boiling not needed
