Gary,
My dad loves waffles and has that one in the Belgian variation. It takes a very very very very very long time to warm up, which is a good sign.
The acoustic warning is accurate, astonishingly...each batch comes out with the same level of brownness.
I spray the grids with canola oil every third batch, tho' very lightly. Cleaning is not easy, that stainless steel exterior was a stupid idea and Cusinart's only major weakness.
The knob has to be set to nearly '3' on my parents'...but you will have to experiment. The green light functions, but the acoustics are more convenient.
I am sure there will be tons of recipes listed, my own non-fail depends on the humidity and individual factors, so feel free to adjust. I don't like sugar in my waffles...
Two eggs
400ml buttermilk
200ml milk
40ml melted butter or 30ml neutral tasting vegetable oil, not walnut...turns bitter
stir till wet ingredients are mixed
add
5g salt (if you like them a bit salty, add more, I don't)
25g baking soda
350g white flour for starters
stir together but just to moisten, don't overdo. We do not want to develop the gluten.
now, add more flower, 50g at a time until the batter is the right consistency. It should be about right somewhere between 450-500g flour, depending on conditions and flour. It will thicken after it sits a bit. Not so thick you have to help with a spoon, not so thin it pours freely.
Don't overfill, put in a bit less until you have a feeling for what is right. Don't ever open the lid before the signal goes off, ignore all that nonsense about when it stops steaming, it is done...that won't work with such a large batch at once.
Some people add sugar, cut down on the sodium by using whipped egg-whites instead of baking soda, etc. Pretty hard to ruin waffles in these machines...a good choice if you have to go modern.
What I would not do, under any circumstances, is buy one of those horrid, cheap Chinese irons with the teflon-coated-aluminum foil plates and the too strong, uneven heating elements which Walmart and others sell for 15$US or so.
Personally, we use a Sunbeam from the late 1940s. Idiot proof.
