What's a Jaffel? It's a toasted sandwich which has the edges sealed in.

Apparently, the Jaffle Iron was designed, named and patented in Australia in June 1949 by Dr Ernest E. Smithers, : Its a bit like a 'Pressure Toaster'. You can also get jaffel irons to use on camp fires. These made of cast iron can provide a tasty snack while camping.

Talking of tasty snacks, this jaffel filling is one of the best (IMHO) and makes a change from bake beans and cheese.

Step 1: Potato Preparation

Cut up some potatoes and cook by boiling. The ones I had were prewashed, so I didn't peel them.
Once cooked, mash them up. I used a fork but you could also use a potato masher.

Step 2: How to Cut an Onion

Here' a easy way to cut an onion:

Cut the onion in half
Cut of one end off while leaving the other end on
Peel the half
Make cuts vertically, away from the end still attached
Slice horizontial, I do this slighly downwards
Slice crossways, this completes the dicing of the onion half

Step 3: Mix and Season

Mix the onion in with the mash potato
Mix in the cheese
Use your own judgement for the quanties of each ingredient
Add in some seasoning

Step 4: Cook

Spay a bit of cooking oil on to the jaffel iron, or what you can do is butter one side on the bread and place this side against the iron's surface.
Spoon in the Cheese, Potato and Onion mixture. I normally put in a little too much filling, just the way it goes.
Place on top another slice of bread
Close the jaffle iron together and cook to perfection.
